| 摘 要： | 以攀枝花尾矿为原料制备透水混凝土,采用填充体积法进行配合比设计,通过投料法和插捣法进行透水混凝土的搅拌成型,考察了水灰比(W/C)、设计孔隙率等对试块性能的影响。结果表明,当设计孔隙率P为15%,水灰比为0.30时试块抗压强度达到最大值29.2 MPa,并且透水系数2 mm/s,能达到一般轻型抗压透水施工要求。

| Abstract: | The pervious concrete was prepared by using Panzhihua tailings as raw material. The mix ratio design was carried out by
filling volume method. The mixing and forming of pervious concrete was carried out by feeding method and tamping method. The
effect of water/cement ratio (W=C) and design porosity on the performance of the experimental block were investigated. The results
show that when the design porosity P is 15%, W/C is 0.30, the compressive strength of the test block reaches its maximum of 29.2 MPa,
and the water permeability coefficient is above 2 mm/s, which can meet the general requirements of lightweight compressive pervious
construction. |
