摘要
通过室内试验制备反滤混凝土试块,以碎石、水泥、河砂、SR-3、水为试验因素,选用4因素5水平的均匀设计,探究影响反滤混凝土抗压强度、孔隙率、pH值等的影响因素。通过试验研究对比,得出适用于小河流治理的反滤混凝土配合比范围:碎石、水泥、河砂、SR-3和水用量分别为1546~1578 kg/m^3、250~280 kg/m^3、80~100 kg/m^3、4.7~5.5 L/m^3、72.5~109.2 L/m^3,为生态混凝土护坡的实际工程应用提供一定的参考价值。
Based on the experiment factors of gravel, cement, sand, SR-3 and water, and according to prepare the filter concrete samples by laboratory test, the influence of compressive strength,the porosity and pH on filter concrete is studied with the uniform design of 4 factors and 5 levels. The range of filter concrete proportion for stream governance is obtained by the analysis of contrast experiment. The proportion are 1546-1578 kg/m3, 250-280 kg/m3, 80-100 kg/m3, 4. 7-5. 5 L/m3, 72.5-109.2 L/m3, for gravel, cement, sand, SR-3 and water respectively, which can provide reference value for actual engineering of eco-concrete slope.
