摘要
采用多孔混凝土的配合比设计方法,分别以20%、25%、30%3种不同的孔隙率为目标进行了配合比设计。重点对植生混凝土的强度、实测孔隙率、混凝土孔隙内的pH值等主要指标进行了对比,并分别阐述了各指标的影响因素。试验结果表明:合理的配合比设计,在保证孔隙率20%～30%要求下,可以配制出强度等级达到C10的植生混凝土。
Based on the mix design methods of porous concrete,this paper makes mix design for three different porosity which respectively reach 20%25 %,30%. The test makes comparison of the strength of plant-ing concrete,the measured porosity and PH value of the concrete pore,and alson describes the influencing factors of the indexes. The results show that a reasonable mix design,while ensuring the porosity of 20% 30% ,can be prepared to planting concrete with C10 strength grade.
