Types of Cement 1. Just like the polymer impregnated concrete, the members are allowed to dry and then dipped in high temperature monomer solutions to pack the voids through polymerisation. vii) High in toughness, flexural rigidity, ductility and yield strength than PCC. The fibres tend to form lumps and not mix well. You can use different types or grades of cement for different elements of a building. i) Lighter sections can be achieved due to the use of high strength materials. iii) Increased fire resistance when compared to steel structures. ii) Lighter sections and therefore lower costs . We recommend using PPC Cement for residential house construction as it offers better durability & resistance to chemicals. i) Plain Cement Concrete is weak in tension. Lost your password? The use of lime in concrete has gone. After the hard strata have been reached, a layer of sand is laid followed by Plain Cement Concrete. In this type of concrete, the monomers / polymers such as polyester styrene, epoxy styrene etc., are added to the concrete mix during the mixing process itself. This cement is suitable for all kinds of concrete construction. It is commonly used in the foundation of a building. There are commonly three types of cement used in general house construction purposes i.e. Mortar Cement Mix: Mortar is a common cement mix used to lay brick and stone. be more better if u estamate their relative proportion on different continents. The choice of materials for construction is based on cost and effectiveness to resisting the loads and stresses acting on the structure. Cement is a powdered mineral substance containing lime or gypsum which when mixed with water forms a paste that will set and harden into a hard and brittle material. There are various categories of cement used in building works for various purposes. There are three types of polymer concrete which include polymer impregnated concrete, partially impregnated polymer concrete and polymer cement concrete. C 3 S gives the cement its initial strength, and makes it harden rapidly. This cement has reduced the contents of C3A and C4AF. In the construction industry, there are different types of cement. In this type of concrete, instead of cement, the polymer is used with the aggregates. Materials Used in Construction. When masonry is constructed with two or more types of building materials is known as composite masonry. Due to the shrinkage, the crack increases and the strength decreases. iii) Reduced thickness in the structural member cuts the footing size. Building material is any material used for construction purpose such as materials for house building. Hydrophobic cement is mainly used for the construction of water structures such as dams, water tanks, spillways, water retaining structures, etc. Some of the numerous functions of cement are given below. First, the high strength tendons are pulled and the concrete is casted in the mould with the normal reinforcement and the pulled tendons. Fibre reinforced concrete is a composite material made up of cement, water, aggregates and flat or rounded fibres. Learn more about cement in this article. In this article, ill give a detailed explanation of each slab and where to use a particular slab. High strength concrete has a compressive strength of at least 70 MPa. Shingle Fiber Cement Siding – Very pleasing to the eye, due to their wide variety of colors. Type O Mortar. OPC (Ordinary Portland Cement) OPC is one of the most commonly used cement throughout the world. Smog eating concrete is a recent development in concrete technology to fight against pollution in modern cities. The lightweight concrete is used to mould blocks called hollow blocks. Concrete is a construction material obtained by mixing cement, fine aggregate (sand) coarse aggregates (gravel, stone chips, rock, etc), and water in certain proportions. After the concrete has sufficiently hardened, the prestress tendons are spliced and the stress is transferred to the member. It can be done by increasing the cement content, restricting the water-cement ratio to not more than 0.3, using super plasticizers, mineral admixtures, and non-porous aggregates. Plain Cement Concrete is a basic concrete mix consisting of cement, fine aggregates, coarse aggregates, admixtures (optional), and water. The performance of the concrete can be improved by making the three phases on the concrete – the paste phase, transition phase, and aggregate phase stronger. This type of scaffolding is normally used for repair works such as pointing, painting, etc., wire ropes or chains are connected to the working platform of the scaffolding and is suspended from the roof of the building. All these ingredients when properly mixed, cement, and water start a reaction to bind themselves produce a plastic mass which hardens over time. The design of precast members takes into account the handling and erection stresses that may arise during the construction process. 5. Cement is a material with adhesive and cohesive forces that bind together other solid material matter into a compact durable form. Ordinary Portland Cement (43 Grade & 53 Grade), Portland Pozzolana Cement and … The most commonly used mix is cement, aggregates and water in the proportion 1:2:4. It is made by adding a photocatalytic additive called Titanium dioxide to the concrete. Some of the common types of concrete mixture used in concrete work in NYC are: Normal Concrete: Normal concrete has a setting time of 30 to 90 minutes. The density of normal Plain cement concrete is 2400 kg/m3. This can be avoided by using air entraining agents like wood resins, hydrogen peroxide, aluminium powder, sulphonic acid, etc.. Fibres are added in the ratio of 0.1% to 3% of the total volume of the concrete. OPC 33 grade is normally not used where high-grade concrete is required due to limitations of its strength. Some of them are outdated and many of them are frequently used everywhere. PCC is very strong in compression. The developments in technology have led to the invention of new types of concrete with specific uses. In this type of concrete, instead of cement polymers are used as binders to reduce the porosity of the member. Reinforced Masonry. It is used in mortar for plastering, masonry work, pointing, etc. As you shop, you'll find that there are three common cement types available, including Portland cement, masonry cement and mortar mix. This type of column majorly used in building construction. The stamping can be done using concrete stamps made of polyurethane, The stamping gives an embossed and classy look to the concrete which is often considered to be decorative. iii) Once started with the process, stopping will create weak joints in the mortar or concrete. High performance concrete is a special type of concrete made using cement, water, fine aggregate, coarse aggregate, mineral admixtures, and superplasticizers. © 2009-2020 The Constructor. There are various categories of cement used in building works for various purposes. Water plays a vital role in workability of concrete. I.e. This cement is produced by grinding clinkers formed by calcining bauxite and lime. The need for air entraining agents is prominent in cold weather regions that are vulnerable to freeze thaw cycles. This made adding special bacteria and calcium lactate to the concrete mix. Cement consumption in India 2017 | Statistic. Usually, retarders are added to the concrete mix to slow down the setting process to give allowance to the transportation and placing time of the concrete. iv) Free from corrosion due to the absence of steel. 4. 1. Concrete is very strong in compression but little in tension. This raw material is burned at a very high temperature to manufacture Hydraulic Cement. iii) Low in toughness, flexural rigidity and yielding. Extra rapid hardening cement. iii) The distribution of the fibres in a batch should be uniform. and when to use? The difference on the slump value of the both should not differ by more than 25 mm or 1/8th of the specific value whichever is greater. After this, the monomers such as styrene, acrylonitrile, thermo plastics are injected into the voids under high temperature and the voids are pack through polymerisation. It is used in marine structures, sewage works, sewage works, and for laying concrete underwater, such as bridges, piers, dams, and mass concrete works, etc. Portland cement has been around since 1824. When the tendons are prestressed, the stress from the tendon is transferred to the concrete thus improving the deflection resistance, load capacity and overall structural performance of the member. Bacterial concrete also known as self-healing concrete has the ability to repair the cracks and fissures by itself. i) High resistance to freeze thaw cycles, chemical attacks etc. The quality of concrete depends on the quality of the cement. It is used in mortar for plastering, masonry work, pointing, etc. Along with the type of cement, it is also necessary to choose the best cement company, check out my guide on Top 10 Cement Companies in India to know more about the best cement companies. Quality check is performed both in the factory and at the site. There is an eccentric vibrating element inside it. i) The workability of the concrete may be affected if there is delay due to traffic. iii) Special equipment like cranes are required for erection. iv) The size of the coarse aggregate is restricted to 10 mm thus increasing the surface area of the aggregate exposed to the interfacial transition zone. We are here for your questions anytime 24/7, welcome your consultation. Shotcrete is a special type of sprayed concreting where mortar or small aggregate concrete is sprayed at high velocities using compressed air to the place of interest. After hardening, high strength steel tendons are introduced into the ducts and are prestressed and anchored to the ends of the member. It is not a true concrete as used in civil engineering terminology. It has high compressive power and low tensile strength. We recommend using PPC Cement for residential house construction as it offers better durability & resistance to chemicals. Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. However, excess lime may hinder the breathing of people inside the building. i) Clogging could disrupt the process and may even become dangerous to the surrounding. Prestressed Concrete. Above the Plain cement concrete, the reinforcement cage of the footing is placed. Permeability: This concrete is almost impermeable to moisture. First, a tightly packed wire mesh is installed over which a rich cement mortar mix of ratios 1:2 or 1:3 is applied to both sides of the wire mesh. vi) The PCC acts as a sturdy ground for placing the cover blocks for the footing. For high, rise buildings, the use of OPC Cement is recommended. In the presence of water, the bacteria germinate by feeding on the added calcium lactate converting it into calcium carbonate – limestone. For instance, portland cements and blended hydraulic cements for concrete in the U.S. conform to the American Society for Testing and Materials (ASTM) C150 ( Standard Specification for Portland Cement ), C595 (Standard Specification for Blended Hydraulic Cement) or C1157 (Performance Specification for Hydraulic Cements). All these materials at present are mostly used in building construction only to improve durability or repairs works. Ordinary Portland cement (OPC), portland pozzolana cement (PPC), rapid hardening cement, quick-setting cement, low heat cement, sulfates resisting cement, blast furnace slag cement, high alumina cement, white cement, colored cement, air-entraining cement, expansive cement, and hydrographic cement. The limecrete unlike conventional concrete will not set in 24 hours. It is a hydraulic cement, which means that once the curing is done with water, it becomes water resistant. 1. 23 Types of Concrete Used in Construction and their Applications. vi) Low resistance to shrinkage stresses. 10 Different Types of footings used in construction, where to use? iv) Ductile reinforcements can withstand the effects of earthquakes. It takes about 7 days for the cement to start hardening, and requires about 28 days to attain 80% of the total strength. The presence of voids in hollow blocks is 25% of its gross area, and the solid area is more than 50%. It has the property of repelling water and is unaffected during monsoon or rains. The plant made concrete is loaded into special delivery trucks called the transit mixers which have the provisions to constantly rotate and keep the concrete in motion and thus prevent setting. i) Air entraining agents cannot be added. Thus, the advantage of this cement is that formwork can be removed earlier, which increases the rate of construction and decreases the cost of construction by saving formwork cost. In this article, we will discuss 16 different types of cement and their uses in construction work. ii) High self-weight thus heavier foundations and columns. The applications of cement over various fields of construction have made it a very important civil engineering material.. It is the fine powder that, when mixed with water, sand, and gravel or crushed stone (fine and coarse aggregate), forms the rock-like mass known as concrete. Cement is a very useful binding material in construction. They are used in different types of construction applications. Therefore, steel reinforcement is provided to increase its tension capacity. Bricks are only a small name, but many of its special secrets are hidden behind it. a) Field Test. Today cement is the only binding material used in concrete. Mineral admixtures like fly ash, ground granulated blast furnace slag, silica fume, rice husk ash have high specific surface area which plays a major role in increasing the strength. Asphalt is a bituminous material that acts as a binder in the concrete. Masonry Cement Mix: Building brick or stone structures requires the commercial-grade strength of masonry cement mix. Reinforced cement concrete is a composite material made up of cement, fine aggregates, coarse aggregates, admixtures, and steel reinforcements. It is for this very reason that most high rise buildings use this grade of cement. Pervious concrete is a special type of concrete that has high porosity and allows water to pass through it and recharge the ground water. Thus, it is important to understand properties of each type of cement and their uses. Reinforced Concrete. Water is required to complete the chemical reaction with cement. Over the years, cement in Malaysia has further developed thanks to technology. 1.Ordinary Portland cement. This cement has increased power against sulphates and is less reactive and initial setting time is greater than OPC. The air can be introduced by chemical reactions, using foam or chemicals like aluminium powder, hydrogen peroxide and zinc compounds. Different Types of concrete slabs in construction:-There are 16 different types of Slabs in Construction. We reveal different types of cement products, their compositions, properties, and typical uses. Some concrete in addition to monitoring the health has the ability to heal themselves. iii) Risk of getting punctured when hit with a pointed object. vi) It requires skilled labours and proper planning. The selection of a suitable type of footing generally depends on the following factors: This is called as the freeze-thaw cycle. Ready-mix is routinely used for poured concrete of this type. The air entraining concrete can also be made using air entraining cement. The aspect ratio of the fibre is generally 30 to 150. The needle vibrator consists of a steel tube, known as a poker, with one end being closed and rounded. When water is added with all the concrete ingredients a reaction between cement and water takes place and concrete is formed. The concrete has to be strong enough to withstand the huge amount of prestressing that will be transferred through the process. The applications of cement over various fields of construction have made it a very important civil engineering material.. Here the stress transfer is through the bond strength between the concrete and steel. Due to the absence of cement, this concrete is not strong enough. High strength concrete is used in the precast industry. Get Price. The ready-mix concrete is preferred when there is less space for storing and mixing the construction materials. 07. during the grinding of clinker. Different cement classification. In Post tensioned prestressed structures, the concrete member is first cast with the conventional reinforcement and special ducts. Ordinary Portland Cement (OPC) 43 Grade Cement: There are commonly three types of cement used in general construction purposes i.e. ctures. But, due to the absence of reinforcements like steel, it is very weak in tension. Sign Up to The Constructor to ask questions, answer questions, write articles, and connect with other people. The liquid water penetrating into the cement structure under freezing temperatures will turn into solid ice. more information like their strength say 32.5 N and 42.5 N Could be useful, HAA HAAAAA HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA. Using light weight aggregates like silica sand, pumice, saw dust, scoria, volcanic cinder blocks, volcanic slag, tuff, crushed stone and synthetic aggregates like coke breeze, foamed slag, bloated clay, expanded perlite, thermocol beads, broken bricks etc. Uses and applications. All Rights Reserved. Ordinary Portland Cement (43 Grade & 53 Grade), Portland Pozzolana Cement and Portland Slag Cement. These air entraining agents will form artificial air pockets inside the mix. In congested reinforcements like beam-column junctions. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass. There are 25 different types of concrete discussed below. The glass fibres also increase the durability of the structure due to its alkaline nature. All the limitations in the Plain cement concrete can be overcome by reinforced cement concrete. Unlike shotcrete, guniting uses a dry mix which will be uniformly mixed with water near to the nozzle and discharged to the receiving surface. 3. The RCC column section is larger than the metal section for multi-storey construction. 1. Many naturally occurring substances, such as clay, sand, wood and […] The properties, applications, advantages and disadvantages of glass fibre reinforced concrete are similar to that of fibre reinforced concrete that is discussed above.

Guniting is very similar to shotcrete but using a dry mix. ix) Better performance of the concrete to varying environmental conditions. For high density concrete the density ranges from 3360 kg/m3 to 3840 kg/m3. They are widely used for decorative works on floors. High Alumina cement . Type I (Portland cement) Type II (Sulphate Resisting Cement) Type III (Rapid Hardening Cement) Type IV (Portland Pozzolana Cement (PPC) Type V (Hydrophobic Cement) Quick setting cement is used where works is to be completed in very short period and for concreting in static or running water. Used for general civil construction works under normal/mild environmental conditions. ⇰ Any lump found in the cement bag should be powdered by pressing between the thumb and the fore finger. It has high workability and does not require any extra compaction. Some other types of concrete are Sulphur impregnated concrete, Roller compacted concrete. Some of the numerous functions of cement are given below. Prestressed concrete structures are commonly used in the construction of prefabricated buildings. ix) Less maintenance cost which can be ignored. Below are the types of concrete slabs. This process provides more bond strength than shotcrete. To supply water everywhere in the building For the disposal of rain water above the ground To dispose water from water closets and washbasin etc To drain soil & waste water to septic tanks or town sewers. There are about ten types of cement that are used for construction purpose. In this article, 25 types of concrete have been discussed. 53 Grade cement has the highest strength compared to the other two types of cement. Steel beams are used in different types of construction like building, workshop, steel roof truss, bridge, ropeway etc. This type of cement is especially suited to improve the workability with a smaller water-cement ratio and to improve frost resistance of concrete. It is a rapid hardening cement with initial and final setting time of about 3.5 and 5 hours, respectively. The types of columns in which is reinforced with steel are known as reinforced concrete column. However, the following are the five main types of cement which are widely used in house construction. High density concrete is a special type of concrete made up of cement, water, fine aggregate, coarse aggregate, and high-density aggregate. Rapid hardening cement is used in prefabricated concrete construction, road works, etc. Portland slag cement. The porous nature of the concrete demands high maintenance and regular cleaning. This is also used for construction of structures that require high grade concrete. Each material has different properties such as weight, strength, durability and cost which makes it suitable for certain types of applications. This titanium dioxide in the presence of sunlight gets activated and reacts with the pollutants in the atmosphere to neutralise them into harmless salts. There are many types of building materials used in construction such as Concrete, Steel, Wood and Masonry. xi) Due to the discontinuous nature of the steel fibres, the corrosion doesn’t not spread. ii) It is expensive than normal concrete. and for interior and exterior decorative work like external renderings of buildings, facing slabs, floorings, ornamental concrete products, paths of gardens, swimming pools, etc. ii) Unskilled workers may add extra water for easing the spraying process. It is designed to overcome the problems of storm-water runoff and replenishment of local watersheds. Different Types of Cement Test. v) In the foundation, it acts as a cover and prevents the intrusion of water or reactive soils. This cement has increased lime content and contains higher c3s content and finer grinding, which gives higher strength development than OPC at an early stage. Concrete is strong in compression and weak in tension. … As a result, cracks will be formed to release the pressure. Cement is a very useful binding material in construction. Fresh concrete can be poured into any suitable forms or moulds to get desired shape and size. Polymer concrete is a special type of concrete that will reduce the pores in the member through the incorporation of polymers into it. Sun-Dried or Unburnt Clay Bricks. For construction, sand is commonly used as an ingredient for concrete, with numerous options available depending on what a project needs. There are various types of cement used in concrete construction. A small quantity of tricalcium aluminate makes the concrete to produce low heat of hydration.
