摘要
通过掺入不同种类的粗骨料,改变多孔混凝土的配合比,监测了所配制多孔混凝土的抗压强度、有效孔隙率及透水性等指标,研究结果表明,使用大粒径碎石作为骨料时,孔隙率高、透水性好,但是抗压强度十分低;使用陶粒作为骨料时抗压强度也比较低,透水性最强;使用小粒径碎石作为骨料,抗压强度较高,透水性中等。
According to the mixing with various types of coarse aggregates,the paper changes the proportional ratio of the porous concrete,supervises the compressive strength of the concrete,effective porous ratio,and permeability,proves by the result that the aggregate with large-diameter gravel has better permeable porous capacity with lower compressive strength,that the aggregate with the ceramic has lower compressive strength with better permeability,that the aggregate with small-diameter gravel has better compressive strength with medium permeability.
