Grade of cement and Types:- Cement is among the oldest binding supplies used for development. Silica (SiO 2 ) 20 – 25%. Application/use: – To provide the uniform surface of the foundation concrete and to prevent the direct contact of foundation concrete from the soil. Concrete Mix design of M5, M7.5, M10, M15, M20, M25, M30 and higher grades of concrete is calculated as below: The procedure for finding the different grades of concrete mixes are same. Concrete grade C-10. This type of cement is used for plain concrete work and plastering works. But how do you measure the quality of cement? Sulphate-Resisting Cement. Each cement has special properties and therefore it is used under certain conditions. The main constituents are the … Grade of Concrete. Unlike other grades of cement, 53 grade ordinary portland cement is used for structural purposes as in reinforced cement concrete. Runways, Concrete Roads (PQC), Pressurized Concrete Girders, RCC Columns, pressurized beams, Application/use: – Runways, Concrete Roads (PQC), Pressurized Concrete Girders, RCC Columns, pressurized beams, Application/use: – Pressurized Concrete Girders and Pier. There are following classifications of concrete grades such as; Normal; The standard and, High strength concrete grade; 1: Normal Grade Of Concrete: Concrete Grade. 4.
