WebTitle: Limit on Strength of Normal Weight Concrete Date: November-December, 2001 Volume: 46 Issue: 6 Page number: 112-117 Author(s): S. K. Ghosh ... This article points … WebAddition of supplementary cementitious materials into the concrete mix like silica fume, fly ash and GGBFS helps in reducing the permeability of the concrete. The high strength concrete has a lower value of permeability compared to normal strength concrete. This is because the high – strength concrete is designed with lower water cement ratio.
