Question

Shrinkage of concrete depends upon the:

• A. relative humidity of the atmosphere & passage of time
  
• B. the moisture in the surrounding
• C. applied stress
  
• D. raining factor

Answer 1

The correct option is A relative humidity of the atmosphere & passage of time

Drying shrinkage is defined as the contracting of a hardened concrete mixture due to the loss of capillary water. This shrinkage causes an increase in tensile stress, which may lead to cracking, internal warping, and external deflection before the concrete is subjected to any kind of loading.

Shrinkage depends upon the relative humidity of the atmosphere & passage of time.

Hence, the correct option is A.
