Abstract

Abstract

Taking water to binder ratio, fly ash percentage and sand ratio as mix-designed parameters, the influences of the parameters on the frost thaw resistance of high performance concrete (HPC) were studied with orthogonal experiments, the loss rates of bending strength and quality were calculated after 300 cycles of rapid freeze-thaw test, and their maximum difference binder ratio and variance were evaluated.The result shows that water to binder ratio has great influence on the frost thaw resistance of HPC, while fly ash percentage and sand ratio have little influence on the frost thaw resistance; the loss rate of bending strength is more sensible to freeze-thaw test than the loss rate of quality, so it should be used as the evaluation index of HPC.
