采用525 #普通硅酸盐水泥、磨细粉煤灰(或磨细矿渣)、硅粉、高效减水剂和标准砂等原材料 ,以常规的制作工艺和蒸气养护 ,配制出抗压强度达200MPa的超高性能混凝土 ;掺入一定量的钢纤维后 ,抗压强度达240MPa ,抗折强度达40MPa。讨论了磨细粉煤灰、磨细矿渣、砂灰比和钢纤维对混凝土强度、流动性的影响 Using 525 # ordinary Portland cement, ground fly ash (or ground slag), silica fume, superplasticizer and standard sand and other raw materials to the conventional production process and steam curing, prepared a compressive strength of 200MPa Of ultra-high performance concrete; After a certain amount of steel fiber is incorporated, the compressive strength reaches 240MPa and the flexural strength reaches 40MPa. The effects of ground fly ash, ground slag, grit ratio and steel fiber on the strength and fluidity of concrete are discussed
