Abstract
This paper uses low-cost metakaolin to strengthen recycled aggregate pervious concrete,and studies the effects of metakaolin on pervious property and flexural tensile strength.The results show that with the increase of the regenerated coarse aggregate substitution rate,the connected porosity and permeability coefficient of pervious concrete increase,and the flexural tensile strength decreases,which indicates that the addition of regenerated coarse aggregate enhances the permeable property of pervious concrete and reduces its flexural tensile strength.With the increase of metakaolin content,the connected porosity and permeability coefficient of recycled aggregate pervious concrete decrease first and then increase,while the flexural tensile strength increases first and then decreases,indicating that the addition of appropriate metakaolin decreases the permeability performance of recycled aggregate pervious concrete,but can significantly enhance its flexural tensile strength.关键词
