Utilization of Waste Materials to Improve the Mechanical Properties of Cement Mortar

With the increasing cost and consumption of the building materials, there is a need to settle them with cheaper alternatives like (marble dust and brick powder). In this study cement was replaced by marble dust waste (0%, 5%, and 10% up to 25%) and fine aggregate was replaced by brick waste powder (0%, 5%, and 10% up to 25%) by weight of the cement mortar mixture at the same time. In this search, the flexural and compression strength in addition to the Water Absorption of cement mortar mixtures was specified. The main results of this paper showed the possibility of partially replacing (cement and sand) with (marble-dust and brick powder) in the cement mortar mixture, and the optimum ratio of replacement was achieved by (20) %
