摘　　要：探索了在试验室条件下采用52.5普通硅酸盐水泥复合适量硅粉作胶凝材料,以富锌硅成分的重质砂石料为集料,掺入高效减水剂与用常态混凝土的制备工艺,进行高强度混凝土的试验研究。The laboratory tests and studies of a kind of high-strength concrete are dealt with. The concrete is made up of 52.5 normal Portland cement blended with appropriate amount of silica fume as binder; zinc-rich heavy sand and stones of silica content as aggregates and high efficiency water-reducing agent, and the concrete is mixed with the procedures commonly used for normal concrete.
