The concrete flat slab option has a marginally lower frame and floor cost compared with the steel composite option but on a total building basis the steel composite option has a lower overall cost (3 159/m 2 compared with 3 185/m 2) This is because of lower substructure and roof costs and lower preliminaries resulting from the shorter programme

A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement aggregate such as sand or gravel and water to form concrete A typical concrete mixer uses a revolving drum to mix the components For smaller volume works portable concrete mixers are often used so that the concrete can be made at the construction site giving the workers ample time to
