Utilization of Waste Materials in the Production of Pervious Concrete: A Review

Pervious concrete is an ideal sustainable solution continuing to gain popularity as a viable paving material and a tool of sustainable development because of its environmental benefits. It has been considered as an environmental friendly building material which is quickly gaining recognition as a green building component. Many researches has been conducted to investigate the possibility of replacing the environmentally unfriendly Portland cement by supplementary cementitious materials, such as fly ash, silica fume, cement kiln dust (CKD) and ground granulated blast-furnace slag (GGBFS), and coarse aggregate by recycled concrete aggregate to enhance the environmental benefits of pervious concrete. The main aim of this study is to review the performance of pervious concrete with these sustainable materials replacing or partially replacing cement and aggregate. It was found that substituting the natural aggregate with recycled aggregate resulted in a considerable increase of permeability coef�cient whereas the mechanical properties of such concretes were adversely affected up to a certain degree. It is also observed that partially replacement of cement with cementitious materials fly ash, silica fume, rice husk ash, cement kiln dust and furnace slag can lead to enhancing the compressive strength of pervious concrete and permeability of pervious concrete. It is concluded that waste materials significantly contribute to improving of the environmental friendliness of pervious concrete.
