【摘要】 活性粉末混凝土(Reactive Powder concrete,简称RPC)是一种具有超高性能和超高强度的水泥基复合材料。通过活性粉末混凝土(RPC)的配制试验,采用单因素优化方法,系统地研究水胶比、高效减水剂和硅灰的掺量对RPC抗折、抗压强度的影响规律。在考虑强度指标、造价及施工方便的基础上,提出了活性粉末混凝土最优配合比:水胶比(W/B)为0.21,硅灰水泥比(SF/C)为0.21,减水剂(SU/B)为3%。更多还原

【Abstract】 The proportion of reactive powder concrete was studied by using the single factor optimum method,and the factors affecting the flexural strength and compressive strength of reactive powder concrete were analyzed,including the water and binder ratio,superplasticizer and silica fume.Based on the flexural strength,compressive strength,cost and actual construction,the optimum proportions of reactive powder concrete were proposed.更多还原
