Abstract
Solid waste disposition has been a growing problem in many developed and under-developing nations. Major part of development was constituted by construction and infrastructure; on the contrary these industries also lead to release of carbon dioxide into the atmosphere. To overcome these disadvantages; in this research, recycled aggregates from construction waste and granite cutting waste were adopted as a replacement of coarse aggregate and cement respectively. Mechanical properties of recycled aggregate (RA) concrete are tested by replacing coarse aggregate varying from 0% to 100% with a difference of 25% and cement is replaced with Granite cutting waste (GCW) varying from 0% to 20% with a difference of 5%. Mix designation and fresh properties were also presented. Results were plotted and compared with the normal concrete to predict the most optimal values of the replacement. Mix containing 25% of RA and 15% of GCW replaced has shown a notable difference in strength comparing with the normal aggregate concrete.
