Use of Supplemental Cementitious Materials for Optimum Resistance of Concrete to Chloride Penetration
The study was conducted to determine whether significant improvements could be achieved in the resistance to the penetration by chloride ions of concretes with fly ash or slag by the addition of silica fume with either Type II or Type III cement and whether early strengths of concretes with fly ash or slag could be improved by the addition of silica fume. The chloride permeability was estimated by means of AASHTO Test Method T 277. The silica fume also increased the strength of similar concretes to some degree, but generally, this increase was not large. Concretes with slag and silica fume reached compressive strengths of 3000 psi in a little more than 2 days.
