The modernization and industrialization of the country making to initiate a huge number of construction activities. In view of this natural resources are exploited and used to the greatest extent thus increasing pollution and resources are deprived. So to curtain and alleviate all these negative effects an experiment was carried out on alternate materials for the purpose of replacement such as Metakaolin (MK) and Marble Dust (MP) to the cement. As river sand plays a prominent role it has been expeditiously extracted from the sea, thereby adverse effects result in fertility of the soil getting reduced, decreasing the vegetation rate, eroding the soil, removing the top fine layer, interfering with the water table level, and disorders the aquatic life. In order to satisfy the demands an alternative material artificial Sand was used. Slag sand is used as a complete replacement to the river sand and has found out the strengths of the mix. Tests as Compressive strength, Split tensile Strength, and flexure strength was conducted on the sample with the replacement percentages of Metakaolin 0%,5%,10%,15%,20%, Marble dust 0%,10%,20%, and slag sand as a complete replacement.
