掺再生骨料及橡胶粉透水砖的研制与性能分析

Preparation and Performance Analysis of Recycled Aggregate and Rubber Powder Permeable Bricks

文章通过研究在透水砖掺入再生骨料及废弃橡胶粉,对其抗压强度、抗折强度及透水系数的影响。在掺入再生骨料比例不变的情况下,分别制作5组不同橡胶粉掺量的对比试验,得出透水砖的抗压强度、抗折强度及透水系数。结果表明,透水系数都能满足规范要求的情况下,橡胶粉的掺量为7.5%时透水砖的抗压强度及抗折强度最大。

In this paper,the influence of recycled aggregate and waste rubber powder on the compressive strength,flexural strength and permeability coefficient of permeable brick are studied.Under the condition that the proportion of recycled aggregate is constant,the comparative tests of 5 groups of different rubber powder are made.The compressive strength,flexural strength and permeability coefficient of permeable brick are obtained.The results show that the compressive strength and flexural strength of permeable brick are the highest when the permeability coefficient meets the requirements of the specification.When the amount of rubber powder is 7.5%,the permeable brick has the highest compressive strength and flexural strength.
