Q1. Qty of cement in M25 grade concrete
Ans. 
The quantity of cement in M25 grade concrete is 350 kg/m³.
• M25 grade concrete has a mix proportion of 1:1:2 (cement:sand:aggregate).

• The total volume of concrete is taken as 1 m³.

• Therefore, the quantity of cement required for 1 m³ of M25 grade concrete is 350 kg.

• This is calculated by multiplying the volume of concrete by the proportion of cement in the mix.
