Roller Compacted Concrete - Structural Guide

Permeability of the RCC concrete is very important when water retaining structures such as dams are constructed. It depends on mix proportions, placement method, degreed of compaction, etc. Further, the higher the content of cement lowers the permeability. Generally, well-compacted concrete has permeability in the range of 1.5 to 150×10-8 mm/sec.
