Abstract:
Concrete cracking presents a significant obstacle to achieving a liquid-tight environmental engineering concrete structure. The minimum shrinkage and temperature (S&T) reinforcement requirements cited in ACI 350-20 should prove to be beneficial with respect to limiting crack widths and reducing the likelihood of leakage. However, in some instances, simply increasing the amount of S&T reinforcement alone may not be enough.
