Effect of Copper Slag Addition on the Performance Enhancement of Alkali Activated Pervious Concrete

Stagnation of storm water on the pavement surfaces poses severe challenges on the urban road transportation system. Pervious concrete is an innovative solution for preventing ponding of water by allowing the water permeation through its structure. Production of pervious concrete equivalent to conventional M20 grade concrete typically demands higher cement content. In order to reduce the consumption of cement, a novel ambient curing based alkali activated pervious concrete was developed with copper slag as fine aggregate with its content ranging from 0 to 20% at 5% intervals. The developed pervious concrete mixes with different percentage of copper slag were tested for determining the mechanical properties. Test results revealed the reduction of porosity with the increase in dosage of copper slag whereas the mechanical properties were observed to have considerable increments.
