研究了在４２５Ｒ普通水泥用量为２７０～３１０ｋｇ／ｍ３、粉煤灰掺量为４０％～５０％（体积比）和掺用复合外加剂条件下，配制高性能混凝土．该混凝土的和易性符合泵送要求；２８ｄ抗压强度达３１～４４ＭＰａ，９０ｄ抗压强度达４０～５６ＭＰａ，且具有较高的抗渗性能和较低的绝热温升．
The preparation of high performance concrete was studied under the conditions of 425R ordinary cement dosage of 270-310kg/m3, fly ash content of 40%-50% (volume ratio) and adding compound admixtures. The workability of the concrete meets the pumping requirements; the 28d compressive strength reaches 31-44MPa, the 90d compressive strength reaches 40-56MPa, and it has high impermeability and lower adiabatic temperature rise.
