【摘要】：采用矿渣矿物聚合物代替传统硅酸盐水泥,通过正交试验研究了液胶比、骨胶比及成型压力三因素对所制备透水混凝土抗压强度、空隙率及透水系数等主要性能的影响,利用极差法分析了三个因素及不同水平对透水混凝土综合性能影响的显著性关系;在此基础上,利用单因素试验进一步测试了骨胶比、骨料粒径对所制备透水混凝土强度、空隙率及透水系数的影响规律.研究结果表明:骨胶比对透水混凝土主要性能影响最为显著,当骨胶比为4:1~7:1时,随骨胶比增大,抗压、抗折强度减小,空隙率增大,透水系数增大;当骨胶比较大时,采用5~10 mm骨料制备的透水混凝土其综合性能优于3~5 mm骨料制备的透水混凝土.
[Abstract]:The slag mineral polymer was used to replace the traditional Portland cement. The effects of three factors, such as the ratio of liquid to binder, the ratio of bone to glue and the molding pressure, on the compressive strength, porosity and permeability of the prepared pervious concrete were studied by orthogonal test. The significant relationship between three factors and different levels on the comprehensive properties of permeable concrete was analyzed by using the range method, and the strength of the pervious concrete was further tested by single factor test, such as the ratio of aggregate to glue, the particle size of aggregate, and the strength of the pervious concrete. The influence of porosity and permeability coefficient. The results show that the ratio of bone to glue has the most significant effect on the main properties of permeable concrete. When the ratio of bone to glue is 4: 1 / 7: 1, with the increase of the ratio of bone to glue, the compressive strength, the flexural strength, the void ratio and the permeability coefficient increase with the increase of the ratio of bone to glue, and when the ratio of bone to glue is large, The comprehensive properties of permeable concrete prepared with 5 ~ 10 mm aggregate are better than those of 3 ~ 5 mm aggregate.
