cement consumption m grade concrete

Different grades of concrete are gradeified into M5, M7.5, M10, M15, etc., while M stands for Mix, and the number behind M stands for characteristic compressive strength (fck) of concrete in N / mm 2 at 28 days when verified with 15 cm x 15 cm x 15 cm cube in a direct compression test

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind only water as

Recommended mix proportion of ingredients for grade of concrete M25: From Compressive Strength vs. c/w graph for target strength 31.6 MPa we get, W/c = 0.44. water content = 197.4 kg/m 3. Cement content = (197.4/0.44) = 448.6 kg/m 3. Volume of all in aggregate = 1 – [{448.6/(3.15 x 1000)} + (197.4/1000)] = 0.660 m 3
