Abstract:
Marble dust is a by-product of marble production facilities which creates large scale
environmental pollution. The purpose of this work is to describe, the effects of using waste
marble dust (WMD) as an admixture material on the performance of concrete. For this
purpose four different series of concrete-mixtures were prepared by adding a dosage of
(passing 0.25mm sieve) with WMD 5, 10,12.5 and 15% by weight. In order to determine the
effect of the WMD on the compressive strength, flexural and split tensile strength with respect
to the curing age.. The results indicate that using WMD as an admixture increases the
compressive, split tensile and flexural strengths of concrete. And found out that the optimum
percentage of addition of WMD is 10%
