Q: The inert material of cement concrete mix is:
  • A. Water
  • B. Aggregate
  • C. Cement
  • D. Admixture
Correct Answer: Option B - Aggregate : Aggregate are inert materials (such as sand, gravel or crushed stones) that are used in addition with cement and water in concrete to make it economically feasible for construction gives volume stability to the hardened concrete. Inert material of a cement concrete mix is aggregate. • Different types of inert material used in cement concrete mix are, (i) Fine aggregate – sand, surkhi etc (ii) Coarse aggregate – gravel, boulder etc.
