Abstract: To produce low cost concrete by blending various ratios of fine aggregate and cement with used foundry sand and Pozzocrete to reduce disposal and pollution problems due to used foundry sand and Pozzocrete.Pozzocrete P60 is a processed quality assured fly ash, investigated for its use as a partial replacement for cement in concrete (1:1.48:3.21). The utilization of Pozzocrete P60 as cement replacement material in concrete or as additive in cement introduces many benefits from economical, technical and environmental points of view. The innovative use of used foundry sand in concrete formulations as a fine aggregate replacement material was tested as an alternative to traditional concrete. This paper presents the results of the concrete of mix proportion 1:1.48:3.21 in which cement is partially replaced with Pozzocrete P60 as 10% by weight of cement, and fine aggregate is partially replaced with used foundry sand as 10%, 30% and 50% by weight of fine aggregate. Five set of mixture proportions were made. First (A0) were standard mix (without Pozzocrete and used foundry) sand with regional fine aggregate (sand)and coarse aggregate and the second (B0) mix contained 10% Pozzocrete P60obtained from DIRK India Private Limited, Nasik, Maharashtra state. Other mixes (B1, B2, and B3) contained Pozzocrete P60 (10%)plus foundry sand (10%, 30%and 50%)respectively obtained fromferrous and non-ferrous metal casting industries.The compressive strength and water absorption has been obtained with partial replacement of Pozzocrete P60 with cement and foundry sand with fine aggregate. Test results indicate the increase in the strength properties of concrete and decreasing water absorption of concrete up to 10% replacement of cement with pozzocrete plus 30% replacement of fine aggregate with used foundry sand for strength at 7, 14and 28 days. Also it can be used in non-structural elements with the low range compressive strength wherestrength is not required and low cost temporary structure is prepared.
