再生材料透水砖强度影响因素研究

Study on the Influencing Factors on the Strength of Permeable Bricks with Recycled Material

为深入分析不同因素对再生材料透水砖强度的影响,本文运用控制变量法,研究了水胶比、目标孔隙率、砂砖骨率、再生砖骨料掺量四种因素对透水砖强度的影响。结果表明:水胶比为0.32,目标孔隙率为20%,砂砖骨率为35%,骨料掺量为1104.9 kg/m^(3)时,再生材料透水砖的抗压强度及抗折强度最高。

To analyze fully the effects of different factors on the strength of recycled material permeable brick,this paper used the control variate method to explore the influences of water-cement ratio,target porosity,sand ratio,and recycled brick aggregate content on the strength of permeable bricks.The results showed that when the water-cement ratio was 0.32,the target porosity was 20%,the sand ratio was 35%,and the aggregate content was 1104.9 kg/m^(3),the compressive strength and flexural strength of the recycled material permeable brick were highest.
