As we know construction is very important in our life. In the world of construction, one material is used above all others: concrete. The cement is the base material of the concrete. In the production of OPC not only consumes significant amount of natural resources and energy but also releases substantial quantity of carbon dioxide to the atmosphere. Therefore, it is essential to find alternatives to make the concrete environment friendly. The geopolymer concrete is manufactured without using

This type of concrete has environmental benefit as it has very low greenhouse gas emission compared to that resulted from the production of portland cement. In addition, GPC also utilizes the abundantly available materials such as fly ash, rice husk, GGBS, WPS ashes and foundry sand that are waste by products & not easily disposed. In this way we makes eco friendly environment. The objective of present work is to utilize the waste material such as foundry sand, fly ash in geopolymer concrete and study the variation in the properties of geopolymer concrete on addition of foundry sand. Using fly ash based geopolymer concrete will result in increasing compressive strength, tensile strength and flexural strength of concrete. Foundry sand and fly ash is waste material by using foundry sand and fly ash for producing geopolymer concrete the waste can be used effectively and results in low cost concrete.
