Abstract
An experimental study was carried out to investigate the strength properties of concrete produced with waste marble dust (WMD) as partial replacement for cement. Concrete specimens (cubes, cylinders and prisms) were cast and tested for compressive, split-tensile and flexural strengths at 0% (control mix), 10%, 20% and 30% replacement of cement by weight with WMD after curing in water for 28 days. The results obtained reveal that the replacement of cement with WMD had appreciable impact on the compressive, split-tensile and flexural strength of concrete. An optimum of 20% replacement of cement with WMD is therefore recommended for concrete production.
