  • The fast freeze-thaw tests with fresh water on high strength concrete ( C60 ) with fly ash or slag and composite admixture,as well as the one without admixtures were conducted. The results showed that for the concrete with admixtures ( slag and fly ash) ,the mass-loss rate was the smallest and the relative dynamic modulus of elasticity was reduced slowest,meanwhile the surface was denuded slightest,indicating a best freezing-thawing resistance performance.For the concrete with 50% slag and concrete without mineral admixtures,the mass-loss rate,the relative dynamic modulus of elasticity and the surface denudation were about the same,meanwhile their freezingthawing resistance performance was a little worse than the concrete with admixtures ( slag and fly ash) .For the concrete with 50% fly ash,the mass-loss rate and the relative dynamic modulus of elasticity reduced fastest,and the surface was denuded seriously,indicating a worst freezing-thawing resistance performance.
