c) Coarse Aggregate: The broken stone is generally used as a coarse aggregate. The nature of work decides the maximum size of the coarse aggregate. Locally available coarse aggregate having a maximum size of 20 mm was used in our work. The aggregates were washed to remove dust and dirt and were dried to surface dry condition.
