Conservation of natural resources and preservation of environment is the necessary for sustainable development. Depletion of natural resources is a common phenomenon in developing countries like India due to rapid urbanization and industrialization, involving the infrastructure developments. India being second largest populated country in the world it has become very difficult to prepare a concrete by using natural resources to construct various structures such as Roads, buildings, bridges etc. Availability of natural sand in that is getting depleted and also it is becoming costly. To prevent exhaustion of natural resources such as natural stone, natural sand etc. an attempt is made to replace the natural materials by using waste crushed material along with Alccofine powder and Ground granulated blast furnace slag (GGBS).By using the waste and chemical compound with different proportions along with cement and with proper water cement ratio the suitability and performance of the above said materials is measured in this project.

Alccofine, Ground granulated blast furnace slag, Crushed Sand, Compressive strength, M25 Grade.
