【摘要】 利用特细砂作为细骨料，超细矿渣作为掺合料，在水胶比为０．２８的条件下，配制出塌落度为２００ｍｍ、２８天抗压强度为８０ＭＰａ的高性能混凝土，并分析了该混凝土的流动性及抗压强度与矿渣取代率的关系更多还原

【Abstract】 A high-performance concrete with the caving degree of 200mm and 28-day compression strength of 80 Mpa can be made by using extra fine sand as aggregate, superfine slag as admixture with a water and glue ratio of 0.28. This paper also analyses the relations between the fluidity and compression strength of the concrete and the slag substitutive rate.更多还原
