前言高强混凝土通常是指抗压强度在60MPa以上的混凝土,即强度范围要高于用普通方法生产出来的混凝土。生产这种高强混凝土可用普通的材料,只要严格控制集料的级配,可避免使用过量的水泥。冷凝硅灰在混凝土领域中的出现改变了这种情况,使得现在有可能用常规生产方法而不需特殊的能力或材料生产出 Introduction High-strength concrete generally refers to concrete with a compressive strength of more than 60 MPa, that is, the strength range is higher than that produced by ordinary methods. The production of such high-strength concrete can use ordinary materials, as long as the gradation of the aggregate is strictly controlled, excessive use of cement can be avoided. The appearance of condensed silica fume in the concrete field has changed this situation, making it possible now to use conventional production methods without producing special capabilities or materials.
