D. Natural Coarse Aggregate Machine crushed granite obtained from quarry was used as a coarse aggregate. Coarse aggregate forms the main matrix of the concrete, whereas fine aggregate form the filler matrix between the coarse aggregate. Locally available Natural aggregate NCA having the maximum size 20 mm was used in the present work.
