بيت /crushed stone waste as fine aggregate for concrete
The mixes were designated with the grade of concrete and the type of fine aggregates used. IS method of concrete mix was used to achieve a mix with cube strength of 20 MPa. Mix proportions were arrived and Ewaste was added to the concretemix with a w/c ratio The percentage of E waste added by weight was 0, 5, 10, 15 and 20.

agencies have begun using recycled Portland cement concrete (PCC) materials. Recycled concrete aggregate (RCA) is nothing more than PCC crushed into aggregatesized particles. These particles consist of the original aggregate particles and the adhered mortar (5). At least 36 states use RCA in highway construction applications.
