types of cement used in building construction

Asphalt concrete is widely used in pavement construction. ; It is used for making joints for drains and pipes. Brick: This is another common construction type. Cement is a substance used for binding and hardening other materials. High density concrete is a special type of concrete made up of cement, water, fine aggregate, coarse aggregate, and high-density aggregate. At the same time, the rate of gain of strength is similar to Ordinary Portland Cement, while quick hardening cement gains strength quickly. Partially-impregnated and surface-coated polymer concrete. It is produced by mixing 5- 10% mineral pigments with ordinary cement. vi) Steel can be moulded into any shapes. Below are the types of concrete slabs. They do not undergo any chemical change, they only provide mass volume to the concrete and reduce shrinkage effects. Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. The lightweight aggregates are used to … 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. This cement has a high resistance to various chemical attacks on concrete compared with ordinary portland cement, and thus, it is widely used. more information like their strength say 32.5 N and 42.5 N Could be useful, HAA HAAAAA HAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA. and when to use? viii) High resistance to impact and fatigue stresses and thermal shocks. Formworks in both cases can be removed earlier. Reinforced Concrete. Foundations, Driveways, Patios, RV Slabs, Sidewalks. 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. Limestone hardens over time and thus repairing the concrete by itself. Hydrophobic Portland cement. Hydrophobic cement is mainly used for the construction of water structures such as dams, water tanks, spillways, water retaining structures, etc. Therefore, it is very important to check the quality of cement before using it. Type O Mortar. The expanding cement is used for construction of water retaining structures and also for repairing the damaged concrete surfaces. iii) The distribution of the fibres in a batch should be uniform. The reduction in self-weight can be achieved by any of the following methods. The developments in technology have led to the invention of new types of concrete with specific uses. Thus, it is important to understand properties of each type of cement and their uses. The precast structures are manufactured at the sites using moulds with reinforcement cages present inside them. All Rights Reserved. Above the Plain cement concrete, the reinforcement cage of the footing is placed. For high, rise buildings, the use of OPC Cement is recommended. 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. C 3 S gives the cement its initial strength, and makes it harden rapidly. Lost your password? 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. In Post tensioned prestressed structures, the concrete member is first cast with the conventional reinforcement and special ducts. It is for this very reason that most high rise buildings use this grade of cement. In this article, we will discuss 16 different types of cement and their uses in construction work. It has high workability and does not require any extra compaction. You can use different types or grades of cement for different elements of a building. Portland pozzolana cement. It is designed to overcome the problems of storm-water runoff and replenishment of local watersheds. In this type of concrete, instead of cement, the polymer is used with the aggregates. Ready-mix is routinely used for poured concrete of this type. Types of Cement 1. Rapid hardening cement attains high strength in the early days; it is used in concrete where formworks are removed at an early stage and are similar to ordinary portland cement (OPC). Concrete is very strong in compression but little in tension. iv) It is expensive than normal concrete for small projects. be more better if u estamate their relative proportion on different continents. It is a rapid hardening cement with initial and final setting time of about 3.5 and 5 hours, respectively. When masonry is constructed with two or more types of building materials is known as composite masonry. The fibres tend to form lumps and not mix well. However, excess lime may hinder the breathing of people inside the building. 2. After hardening, high strength steel tendons are introduced into the ducts and are prestressed and anchored to the ends of the member. 1. By registering, you agree to the Terms of Service and Privacy Policy. OPC (Ordinary Portland Cement) OPC is one of the most commonly used cement throughout the world. Hydraulic Cement. As you shop, you'll find that there are three common cement types available, including Portland cement, masonry cement and mortar mix. The mix design ratio of the high-performance concrete is designed in such a way that it performs well both structurally and in durability criteria. For high density concrete the density ranges from 3360 kg/m3 to 3840 kg/m3. and use 43 grade cement for the plastering, infill brick work, flooring work, etc. Type N mortar is also preferred in the construction of buildings or sculptures which use soft stone. Portland cement has been around since 1824. With noncombustible steel or concrete structural framework, walls, and floors, Type II is similar to Type I, but requires lower fire-resistance ratings. We reveal different types of cement products, their compositions, properties, and typical uses. Concrete is widely used in all types of construction work like building, bridges, dams, roads, flyovers, etc. Sulphate Resisting Cement and Super Sulphate Cement are generally used for the construction of structures in Sea water. 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. Now the key to different concrete mixtures is changing the amount of cement in them, obtaining different properties as desired. 4.Portland pozzolana cement. ⇰ Any lump found in the cement bag should be powdered by pressing between the thumb and the fore finger. Lost your password? Much research has been done to prove that lime (especially Hydraulic Lime) can also be used successfully as a Binding material in common type of construction. Smog eating concrete is a recent development in concrete technology to fight against pollution in modern cities. The foundation distributes the load … 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. Fibres are added in the ratio of 0.1% to 3% of the total volume of the concrete. All these materials at present are mostly used in building construction only to improve durability or repairs works. Glass Fibre Reinforced Concrete (GFRC). Krishna June 4, 2017 STRUCTURE 62 Comments. The limecrete unlike conventional concrete will not set in 24 hours. Reinforced cement concrete structures are extra fire-resistant than generally used building materials such as steel and wood. ii) High self-weight thus heavier foundations and columns. Nowadays this variety is not generally produced. Apart from different grades of cement, it is also available in two colors- grey and white.
