33 Grade Ordinary Portland Cement. viii) Uniform quality of the building can be achieved. This mixture features gravel and sand mixed with water to create a strong bond. The developments in technology have led to the invention of new types of concrete with specific uses. Wherever possible, we tend to give reasons as to why a particular cement type is more suitable for a given purpose than other types. 1. 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. Portland pozzolana cement. It is used in mortar for plastering, masonry work, pointing, etc. Cement is a cover material which makes a bond between aggregates and reinforcing materials. Login to The Constructor to ask questions, answer people’s questions, write articles & connect with other people. In congested reinforcements like beam-column junctions. 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. This cement has a high resistance to various chemical attacks on concrete compared with ordinary portland cement, and thus, it is widely used. In this type of concrete, instead of cement, the polymer is used with the aggregates. However, the following are the five main types of cement which are widely used in house construction. Reinforced Concrete. Cement is a material with adhesive and cohesive forces that bind together other solid material matter into a compact durable form. These are the types of blocks used in load bearing mode of building construction in Kerala. The RCC column section is larger than the metal section for multi-storey construction. Ferro Cement Concrete. 13 Types of Cement [PDF]: Properties, and Applications in Concrete Construction, Statistical Concepts of Mix Design as per IS456:2000, 8 Advanced Non-Destructive Testing Methods You Should Know About, Mezzanine Floor for Buildings: Important Features and Types. This plastic and hardened mass are known as concrete. Due to the absence of cement, this concrete is not strong enough. 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. Fresh concrete can be poured into any suitable forms or moulds to get desired shape and size. The quality of concrete depends on the quality of the cement. Followings are the 19 types of cement: Ordinary Portland cement. In pervious concrete, the fine aggregates used are minimized or totally neglected and thus making it porous. They may or may not be prestressed based on requirements. Steel Column: No fines concrete is made up of cement, coarse aggregate, and water. It is made using aggregates, crushed stones and asphalt. A concrete member can be prestressed in two ways: Pretensioned prestressed structures are prestressed before the concrete hardens. The choice of these are based on their cost effectiveness for building projects. There are 4 types of fiber cement siding you can use. The principal types of […] Please enter your email address. iv) Ductile reinforcements can withstand the effects of earthquakes. xi) Due to the discontinuous nature of the steel fibres, the corrosion doesn’t not spread. iii) Reduced thickness in the structural member cuts the footing size. After the hard strata have been reached, a layer of sand is laid followed by Plain Cement Concrete. These units are sometimes burnt in a kiln, and simply sun-dried. OPC (Ordinary Portland Cement) OPC is one of the most commonly used cement throughout the world. It is a hydraulic cement, which means that once the curing is done with water, it becomes water resistant. With noncombustible steel or concrete structural framework, walls, and floors, Type II is similar to Type I, but requires lower fire-resistance ratings. This cement is suitable for all kinds of concrete construction. It is not a true concrete as used in civil engineering terminology. Precast concrete structures are cast, cured, transported to the site and erected using cranes. Get Price. Thus, it is important to understand properties of each type of cement and their uses. 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). #1 Wood (a) Construction of a large pier (b) Construction in cold weather (c) Construction in a warm climate region such as the Phoenix area (d) Concrete structure without any specific exposure condition (e) Building foundation in a soil with severe sulfate exposure 5. It is widely used in pavements where it can allow storm water to pass through it. Sulphate Resisting Cement is manufactured by grinding Portland Cement clinker with gypsum. The Purity and quality of cement can be judged by applying the following rough and ready field test of cement: ⇰ The colour of the cement should normally be greenish-grey. Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the binding materials used in building and civil engineering construction. ix) Better performance of the concrete to varying environmental conditions. It takes about 7 days for the cement to start hardening, and requires about 28 days to attain 80% of the total strength. Sun-Dried or Unburnt Clay Bricks. Concrete is widely used in all types of construction work like building, bridges, dams, roads, flyovers, etc. Uses and applications. Fibres are added in the ratio of 0.1% to 3% of the total volume of the concrete. Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. Become VIP Member. Today cement is the only binding material used in concrete. ii) Steady supply of concrete is possible without interruption. The air entraining concrete can also be made using air entraining cement. This cement has increased power against sulphates and is less reactive and initial setting time is greater than OPC. Admixtures are added to improve the workability, flowability, and pumpability of the concrete. Glass Fibre Reinforced Concrete (GFRC). The name Portland does not refer to a brand name, as many might think. 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. The type of cement used in almost all concrete is Portland cement. 24 d. Partially impregnates and surface coated polymer concrete: Common Interview Questions & Answers (Top 10), How To Calculate Steel Quantity For Circular Slab | BBS Of Circular Slab, Construction Tools List & Uses In Building Work, 40+ Modern TV Unit Designs For Your Your Home, What Is Shear Wall - Its Types, Advantages And Location In Buildings, Slabs, beams, columns, and foundations of buildings, Normally used for monolithic concreting of the roof slabs and beams, Precast slabs, beams, columns, wall panels can be used for conventional buildings. There are various types of cement used in concrete construction. Foundations, Driveways, Patios, RV Slabs, Sidewalks. Glass Fibre reinforced concrete is a composite material made up of cement, water, aggregates, and glass fibres. The flowability of the concrete can be achieved using viscosity modifying agents like sikaplast, retarders, air-entraining agents, very fine mineral admixtures, and superplasticizers. There are several different types of cement which vary in composition and their end-use purposes. This is called as pre-tensioning. This is also used for construction of structures that require high grade concrete. 1.
