摘　　要：通过试验,采用质量稳定的52.5普通硅酸盐水泥,选用质地坚硬,粒形较好,级配良好的5 mm^20mm碎石,细度模数为2.8以上的洁净砂子,并采用掺高效减水剂和高性能掺合料“双掺技术”,常规配制C80级高性能混凝土。This paper shows the experiment on which the concrete grade C80 is mixed in a normal way. The experiment is based on the ＂ double mixing technology＂ in which high efficiency water reducing agent and high performance mixing materials are used. The test also adopts the 52. 5 normal Portland cement, 5 mm - 20 mm hard crush in good quality, good shape and graduation, and sand whose modulus of fineness is above 2. 8.
