Question

Modulus of elasticity of concrete is increased with

• A. Higher W/C ratio
• B. Shorter curing period
• C. Lesser vibration
• D. Increase in age

Answer 1

The correct option is D Increase in age

Modulus of elasticity of concrete is dependent on its compressive strength. Higher W/C ratio, shorter curing period or lesser vibration will produce concrete of lesser compressive strength. With increase in age compressive strength increases and therefore modulus of elasticity of concrete increases.
