植生混凝土性能的试验研究

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。

Experimental Research on Properties of Planting Concrete

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.
