Specification of Concrete for Water Retaining Structures ...

2020-2-19  For construction of water retaining/excluding structures class N (normal hardening) cement is recommended, and should be used ahead of Class R (rapid hardening) due to shrinkage issues. In general, the concrete should be specified in accordance with BS EN 206 and BS 8500 Parts 1 and 2.

Water retaining concrete class C35A

However BS 8007 specified a 35N/mm 2 concrete with a minimum cement content of 325kg/m 3 (compared with 300kg/m 3 in BS 8110) and a maximum water/cement ratio of 0.50 (compared with 0.55 in BS 8110). This variation in constituent material limitations gave rise to the class grade C35A, where A stood for aqueous.
