The Aggregate’s Influences on Properties of Porous Pervious Concrete Made of Recycled Aggregates

Abstract:

In this study,different particle size’s aggregates ,different aggregate correction coefficients and different sand ratio were selected to study the aggregate’s influences on properties of porous pervious concrete made of recycled aggregates.The results shows that the 28-day compressive strength of concrete with single particle size is lower than those with two kinds of particle mixing ,as for the permeability coefficient, the former is much higher than the latter .With the aggregate correction coefficient’s increase,the 28-day compressive strengths of concrete increases first and then decreases, the permeability coefficient increases . The 28-day compressive strengths of concrete increases with the increase of the sand ratio. the permeability coefficient increases first ,decreases then.
