Weight of One Bag Cement = 50 kg
Density (as per IS 875 part-1) = 1440 kg/m3
Volume of One bag = 50/1440 = 0.03472 m3
No. of bags in 1 m3 = 1/0.03472 = 28.8 bags
Cement is a mixture of compounds consisting mainly of silicates and aluminates of calcium formed out of silica, calcium oxide, aluminum oxide and iron oxide. We can state that it is a hydraulic material made by finely grinding clinker (produced by burning a mixture of iron, calcium, aluminium and silica containing materials) together with Gypsum and other additives such as slag, pozzolana and fly ash.
The most commonly used cements is known as Portland cements. However, with an advance of new research & technology and in a quest for conserving natural resources and reducing pollution now a days pozzolana cement is become more and more popular
Portland cements is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.
Ordinary Portland Cements (OPC) is graded according to their strength. The grade indicates the compression strength (mpa) of the concrete that will attain after 28 days of setting.
