摘要
矿物掺合料对混凝土具有重要的强度效应 .本文认为掺有矿物掺合料的混凝土复合材料的强度由水泥混凝土基体 (水泥浆体和砂石集料 )产生的强度和矿物掺合料的物理和化学两方面效应对强度的贡献两部分构成 ,据此提出了全面估算混凝土矿物掺合料强度效应的新方法 ;并从理论和试验两方面分析了水胶比。
Significant strength_effect by mineral admixture can be contributed to concrete. In this paper, the strength of concrete composites containing mineral admixtures is considered to include two parts. One is generated by cement concrete matrix, and the other by physical and chemical effects of mineral admixtures on concrete. On this basis, a new method is presented for evaluating strength_effect of mineral admixture on concrete. Furthermore the effects of water to binder ratio, content of mineral admixtures and ages on the strength+effect are quantitatively analyzed from theory and experiment.
