Concrete is the most wanted material in construction industry which is commonly produced by the combination of binding material, aggregate, admixtures and water. Ordinary Portland cement (OPC), granite and mining sand are mostly used as binding material, coarse aggregate and fine aggregate, respectively.

How to Calculate Cement, Sand and Aggregate required for 1

Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4 , to get a cubic meter of concrete we require. 1.Cement = 6 bags = 300 kgs. 2.Fine Aggregate = 115/0.167 = 689 kg

Materials such as ground granulated blast furnace slag (ggbs) and pulverised fuel ash (pfa), have cementitious properties and can be used in a concrete mixture to reduce the amount of cement. Ordinary Portland Cement, or OPC as it is also known, has a higher embodied carbon than ggbs or pfa. The material pfa is also known as just fly ash.
