    Oct 05, 2020 Gambhir (2005) reported that coarse aggregate constitutes about 75% to 85% of the concrete matrix. Concrete being one of the major building materials that is used virtually in all aspects of construction and could be delivered to the job site, and be molded in situ or pre-cast to any form or shape, makes it a material of choice in construction.
