It is observed that in cold weather, the curing is _________ in the initial stages of the setting of concrete.

(a) Moderate

(b) Slow

(c) High

(d) Fast

I got this question by my college director while I was bunking the class.

The doubt is from Placing of Concrete in section Cement Concrete Construction of Construction & Building Materials

Answer 1

Right choice is (b) Slow

For explanation I would say: The slow curing of concrete results in higher ultimate strength. The concrete should be cured adequately especially when humidity is low and heat is used to control the temperature.
