Density of Cement Sand and Aggregate | Cement Density,
A cement is a binder, a substance used in construction that hardens, hardens and adheres to other materials to join them together.Cement is rarely used on its own, but to bond sand and gravel. The cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.
