Sand requirement in concrete made with natural sand is lower than the quantity required in crushed sand. If compared with rates crushed sand cost almost 75% less than natural sand.Since the crushed sand has higher strength than natural sand, coarse aggregate of 10mm and 20mm size is relatively lower in quantity in concrete made with crushed sand.

3.2 Concrete aggregate. Some natural aggregate deposits, sometimes known as "pit-run gravel," are a combination of gravel and sand that can be used directly into concrete with minimal preparation. Natural sand and gravel are typically removed via dredging or excavation from the bottom of a pit, river, lake, or ocean.
