Use of Marble Dust in Concrete

The main objective of this experimental work is to investigate the performance of concretes contained marble dust as a cement replacement, mix was prepared with cement and sand blended with marble dust with replacement from 0%, 10%, 20% and 30%. The experiment indicates that replacement of cement by marble waste powder at different ranges, in concrete production, results in Up to 10-20% replacement of cement with marble increases the compressive strength and tensile strength of concrete. Further increasing the percentage of marble decrease the compressive strength of concrete. Due to use of marble powder in concrete the water absorption became be less, the amount of permeability became reduce which make an important role to make concrete stable for a longer time
