Q. What is the importance of curing on strength?

 

A. Concrete can usually continue to gain in strength for a long period, provided the temperature and moisture conditions are favorable for the formation of the binder and that the originally mixing-water-filled space is available (ACI 308). Thus, any statement concerning strength should specifically state or imply a particular environment. The effect of temperature conditions on the strength development of concrete is also given in ACI 305R and ACI 306R.
