Abstract
Principal recycling and reuse of industrial waste is one of the most important human challenges to protect the environment. In recent years, due to the unique properties of pervious concrete, the use of pervious concrete pavement as a good alternative to asphalt procedures has been considered. In this study, in order to assess a new method for the manufacture of high -environmentally friendly concrete pavements with aluminum slag replacement with 0, 5, 10, 15 and 30 % cement weight, the concrete samples were made and the tests including compressive strength, bending strength, water absorption percentage, permeability and porosity done. The results showed that aluminum slag replacement with 5 % of cement weight, compressive strength, bending resistance and water absorption percentage compared to the control sample did not change significantly. But using the replacement of aluminum slag with 10, 15 and 30 percent of the cement weight, compressive strength and bending strength comparing to the control sample were decreased by 16, 24 and 50% and by 6, 15 and 24 %, respectively. By replacing aluminum slag with 10 and 15% by weight of cement, the permeability comparing to the control sample was increased by 61 and 97%, respectively. It was also observed that due to the high porosity of the samples containing aluminum slag replacement with 30 % of the weight of the cement, water passed immediately and quickly.
