Types of cement that are available and used in India.
33 Grade Ordinary Portland Cement
Used for general civil construction works under normal/mild environmental conditions. OPC 33 grade is normally not used where high-grade concrete is required due to limitations of its strength. Nowadays this variety is not generally produced.
43 Grade Ordinary Portland Cement
Nowadays 43 grade is being used widely for general construction work like Plastering works. However, 43 grade OPC is gradually being replaced by blended Cement.
53 Grade Ordinary Portland Cement
Used in RCC and pre-stressed concrete of higher grades, cement grouts, instant plugging mortars etc. where initial higher strength is the main criteria.
Portland Pozzolana Cement (PPC)
PPC Cement has a greater degree of fineness, impermeable and corrosion-resistant quality that makes the concrete denser resulting in long-lasting structures. Since it has the high impermeable quality it is used in mass concreting work instead of ordinary cement due to adverse soil conditions.
Portland Slag Cement (PSC)
PSC provides better protection against chloride and sulfate attack. PSC is preferred over OPC for usage in constructions where the structures are susceptible to sulfate and chloride attack. eg: Marine structure, structures near the sea, sewage disposal treatment works, water treatment plants, etc.
White Portland Cement is made from raw materials containing very little iron oxide and manganese oxide. Burning in the kiln is done with furnace oil or gas instead of coal. Limited quantities of certain chemicals, which improve the whiteness of cement, are added during manufacturing. This type of cement is generally meant for non-structural works. It is used for architectural purposes such as mosaic tiles, wall paintings, GRC, and special effects.
Sulphate Resisting Portland Cement (SRC)
In SRC, amount of C3A is restricted to lower than 5% and 2C3A + C4AF lower than 25%. SRC can be used for foundation, piles, basements, underground structures, sewage, and water treatment plants and coastal works, where Sulphate attack due to water or soil is anticipated.
Rapid Hardening Cement
The Rapid hardening cement is used for repair and rehabilitation works and where the speed of construction and early completion is required due to limitations of time, space or other reasons.
Hydrophobic Portland Cement
It is manufactured under the special requirement for high rainfall areas to improve the shelf life of cement. The cement particles are given a chemical coating during manufacturing, which provides water-repelling property, and the cement is not affected due to high humidity and can be stored for a longer period. Due to the abundant availability of cement in all parts of the country, this cement is very rarely produced these days.
Low Heat Portland Cement
Low heat Portland cement is particularly suitable for making mass concrete for dams and many other types of water retaining structures, bridge abutments, massive retaining walls, piers, and slabs, etc.
