Question

Strength of cement concrete primarily depends upon

• A. Quality of water
• B. Quantity of aggregate
• C. Quantity of cement
• D. Water cement ratio

Answer 1

Answer:

B. Quantity of aggregate

Water cement ratio is the ratio between weight of water to the weight of cement used in concrete. The strength of concrete increases with decreasing water cement ratio. The strength of concretes generally depends on water cement ratio Minimum cement content in all structural concrete content should not be less than300 kg/cm. Maximum cement content in all structural concrete should not be more than 450 kg/cm^2.
