The study investigated the use of rice husk ash as an additional cementitious ingredient in concrete compositions, replacing cement with rice husk ash in the following proportions: 0% (without rice husk ash), 6%, 12%, 18%, and 24%. These percentages represent the substitution levels of rice husk ash for cement in the M25 concrete mixture.

A common mix proportion for M25 is 1:1:2 (cement: sand: aggregates). As a rough estimate, you can use around 550 kg (11 bags of 50kg each) of cement per cubic meter of concrete for M25 grade. We want to know how many bags of cement are required in concrete grade M25 and cement bags required for M25 grade concrete.
