Concrete Mix Ratios (Cement, Sand, Gravel) - StructX

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.

Cement - Wikipedia

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.
