摘要
利用正交试验方法,研究了水胶比、用水量、增钙灰取代水泥率和砂率对高性能砼的工作性和强度的影响规律,提出了利用大掺量粉煤灰制备高性能砼是现实的。
With the aid of orthogonal method, the effects of watercementitions material ratio, water content, rate for replacement of cement by fly ash and sandtotal aggregate ration on the strength and workability of HPC are studied in this paper. It is suggested that HPC with large fly ash content is possible.
