minimum grade of concrete mix used for water retaining structures

Concrete construction for liquid-retaining structures ...

In BS EN 206-1 for exposure class XC 4, the minimum cement content is required to be 300 kg/m 3 and the maximum water/cement ratio 0.50. The minimum strength class of the concrete is given as C30/37. 16.2.2. Maximum cement content. Maximum cement contents are restricted in order to minimize cracking due to thermal contraction and drying shrinkage.
