摘要
在强度和含气量相等的条件下,粉煤灰水泥混凝土的抗冻性比普通硅酸盐水泥混凝土略低,只要适当提高含气量,同样能制成高抗冻性的粉煤灰水泥混凝土.
If the strength and air content of fly ash cement concrete are the same as those of the ordinary Portland cement concrete,the former has a little lower frost resistance.If its air content is properly increased,fly ash cement concrete with high frost resistance can be made as well.
