Cement needs no introduction, especially in the construction world. This element holds everything together, literally & figuratively. A wide variety of cement is available in markets that basically come from mixing various ingredients and altering the proportions. This enables cement to be used for almost everything, right from general construction to sulfate-resistant executions like sewage systems.
Infrabazaar brings for you a compilation of some basics, which one must be aware of before they decide about this important ingredient of your or your clients’ dream building!
Portland cement: Basically made up of clay and limestones. Also known as ordinary Portland cement (OPC) popularly used in general construction grounds. This OPC is subdivided in two forms/grades and are available in the market as OPC 43 grade and OPC 53 grade.
Portland Pozzolana Cement: Also called as PPC. Made of ground pozzolanic clinker with Portland cement. Highly resistant to various chemicals on concrete. Mostly used in the construction of Marine or Sewage systems, dams, bridges etc.
White Cement: Commonly used and is similar to Portland cement except differing in color. It is made from iron oxide-free raw materials. It is mostly used to repair marble tiles and sheath floors or a roof.
Rapid Hardening Cement: Also called as high early strength cement. Similar to Portland cement, except for the lime content and has more strength than Portland cement. It attains strength quickly. It gains its strength in 2-3 days, and it is nearly as good as Portland cement within a week's time. It is beneficial in lowering the formwork's total cost as it can be removed and used on other sites.
Waterproof Cement: It is similar to Portland or hardening cement but comes with a combination of metal salts or stearates. They are typically used in the construction of dams, drainage systems or in construction of structures that are open to the rain.
Sulfate-Resistant Cement: It does not produce a lot of heat when mixed with water and attains strength very slowly. Used in coastal works, sewage systems, basal works, piling works or in the construction of basements, underground structures and water treatment plants.
High Alumina Cement: Prepared by baking powdered bauxite and lime and grinding the clinker. It is mostly used in marine, and sewage systems and in refractory applications. This cement has low pH, making it chemical resistant, even resistant to the king of chemicals i.e; sulfuric acid.
