本文采用正交试验方法设计了微硅粉掺量、引气减水剂掺量以及砂率三因素及其不同水平的混凝土性能实验方案,得出了同时掺微硅粉与引气减水剂时影响C40混凝土性能的主要因素。对需要配置有抗冻性、抗压强度、抗氯离子渗透性要求的混凝土具有一定的指导意义。
In this paper, orthogonal experimental design method of the amount of micro-silica fume, admixture of air-drying superplasticizer and the sand rate of three factors and different levels of concrete performance experimental program, obtained at the same time doped silica fume and air- The main factors affecting the performance of C40 concrete. For the need to configure the frost resistance, compressive strength, resistance to chloride ion permeability of concrete has some guiding significance.
