Chloride and Oxygen Permeability of Concrete Incorporating Fly Ash and Silica Fume in Ternary Systems

摘要

The results presented in this paper form part of an investigation into the optimisation of ternary blend systems based on normal portland cement, fly ash and silica fume, for the development of high performance concrete. Chloride permeability and oxygen permeability values at the age of 7, 28, 90 and 180 days of concrete containing portland cement, fly ash and silica fume are reported. Fly ash, up to 40
