Abstract
The main objective of this research is to investigate the possibility of utilizing waste marble
dust (MD) in cement and concrete production. In present study experimental investigation
conducted on optimum marble dust replacement with cement. After cutting and sawing
marbles, in large amount of marble slurry produce. This marble slurry disposed to open land
area, it make land pollution and harmful to land. It has good binding property and gives
enough strength to concrete and due to this it is suitable to bear heavy load. In further study
cement is replaced by marble dust, and then concrete was prepared. The replacement ratios
which have been studied were 0%, 5%, 7.5%, 10%, 12.5%, and 15% by weight. Water –
cement ratio kept 0.42. Concrete made with marble dust as cement replacement achieved
better performance compared to normal concrete. Physical properties of conventional
concrete and marble dust replaced concrete are compared. On fresh concrete slump test was
preformed to check workability of concrete and after then compressive strength and split
tensile strength was checked. Thus marble dust is appropriate substitute of cement in concrete
mix for construction.
