In this constructed environment, the rising prizes of building construction materials are the factor of great worry. The coarse aggregates and sand are the main ingredients used in concrete. We all want that our structure must be strong, stable and should build with the construction material of reasonable prizes. Every construction industry totally trust on cement, aggregates whether it is coarse or : ne for the production of concrete. In this research, we have replaced the cement with geopolymer cement and fresh coarse aggregate with recycled aggregate and sand with foundry sand. It was found from literature that foundry sand and recycled aggregate are used separately in different study but there is no use of these material in combination with geopolymer so this is good option to check the various properties of concrete by replacing foundry sand and recycled aggregate in various parentage. Therefore, we have planned to prepare some number of cubes using geopolymer concrete at various proportions of recycled aggregate like 0%, 25%, 50% by weight of coarse aggregate and foundry sand used in percentage like 0%, 2%. The properties for fresh concrete are tested for compressive strength at the age of 7 days.
