Concrete production is the process of mixing together the various ingredients—water aggregate cement and any additives—to produce concrete Concrete production is time sensitive Once the ingredients are mixed workers must put the concrete in place before it hardens In modern usage most concrete production takes place in a large type Concrete usually Portland cement concrete for its visual resemblance to Portland stone is a composite material composed of fine and coarse aggregate bonded together with a fluid cement cement paste that hardens over time—most frequently in the past a lime based cement binder such as lime putty but sometimes with other hydraulic cements such as a calcium aluminate cement or
