建筑垃圾透水砖的工艺与性能研究

摘要

This paper explores the impact of aggregate particle size and content of fly ash on the splitting tensile strength, flexural strength, anti-freeze strength loss rate and permeability coefficient of permeable brick using con⁃struction waste as the main raw material, and builds a model of permeable brick using construction waste. The ex⁃periment results determine the optimum range of aggregate particle size is 4.75 to 9.5mm, and the optimum content of fly ash is 10%.%利用建筑垃圾为主要原料制备建筑垃圾透水砖，探究了骨料粒径和粉煤灰的掺量对透水砖劈裂抗拉强度、抗折强度、抗冻性强度损失率及透水系数等性能参数的影响并构建了建筑垃圾透水砖模型。通过试验确定的骨料粒径的最佳范围为4.75mm～9.5mm，粉煤灰最佳掺入量为10%。
