heal.abstract	Pervious concrete is a new type of product which allows rain water to pass through its mass due to its high porosity. To achieve this high porosity, coarse aggregates are mainly used with a little or no participation of fine aggregates. The present paper comprises an approach to the addition of demolition wastes as substitutes for coarse aggregates in pervious concrete. Initially the chemical compatibility of construction wastes was examined in relation to the requirements of standard EN 12620 for concrete aggregates. The mineralogical analysis of both construction wastes and limestone aggregates was examined through XRD. Finally, the porosity of these aggregates and the average diameter of the pores were measured. According to these results, it is concluded that the construction wastes have more porous than the limestone aggregates, which enhances their use in pervious concrete as the porous helps the desired property: water permeability.	en
