Effects of Partially and Totally Substitution of Marble Waste as a Fine Aggregate on Workability and Mechanical Performance of Concrete

It has been recommended that; the disposal of industrial waste would be greatly reduced if it could be incorporated in concrete production. One of these possibilities is the substitution of the fine aggregate by marble waste (MW), which contributes to the reduction of natural resources consumption, while solving a waste management problem. The basic objective of this investigation is to examine the characteristics of concrete using MW as fine aggregate in proportions 0%, 20%, 40%, 60%, 80% and 100% by weight of cement. Several fresh and harden properties have been reviewed in the current paper. The results observed from the various tests depict that increase the slump value with the increase the percentage level of MW. Moreover, strength was increase up to 60% substitution of MW and then decreases gradually. Therefore, it is recommended to MW as fine aggregate up to 60% substitution.
