Redi - Mix Concrete

Redi - Mix Concrete is a mixture of sand, stone, cement and water. Stated in other terms, concrete is a composite of paste and aggregate combined to form a solid material. The paste is comprised of cement (a powder) and water. There may also be other ingredients added such as flyash, ground granulated blast furnace slag, silica fume and a variety of admixtures to affect the properties of Redi - Mix Concrete. The aggregates are fine aggregate (sand) and coarse aggregate (stone). The sand and stone act as fillers in the Redi - Mix Concrete. The sand fills the voids between the larger stone pieces.
