Concrete is the most important civil engineering material in construction buildings and industries because increase the strength properties. Rubber and foundry sand are produced excessively worldwide every year. In such a case the reuse of rubber and foundry sand would be a better choice. In order to reuse rubber wastes, rubber tyre chips was added to concrete as coarse aggregate and In order to reuse foundry sand, foundry sand was added to concrete as fine aggregate and its different properties like compressive strength. As a result it was found that rubberized and foundry sand concrete is durable, less ductile, has greater crack resistance but has a low compressive strength when compared with ordinary concrete. Due to rapid growth in automobile industry use of tyre increase day to day and there is no reuse of the same to decrease the environmental pollution .in this paper we will study about physical and mechanical properties of concrete containing recycled tyre or rubber material aggregate. This study present the information about the civil engineering application of foundry sand, which is technically sound and is environmental safe. Foundry sand can be used as a partial replacement of fine aggregate and rubber tyre chip partial replacement coarse aggregate .foundry sand can be used in concrete to improve its strength and other durability factor. Foundry sand is high silica sand that is a by – product from the production of both ferrous and non-ferrous metal casting. The fresh & hardened properties of concrete such as workability, compressive strength, are the identified.
