Effect of Sea Water on Bethamcherla Stone Powder Waste Geopolymer Concrete

Abstract

Four Geopolymer Concrete mixes are prepared by replacing the Ground Granulated Blast-Furnace Slag    (GGBFS) with Bethamcherla stone powder waste in the ratio of 0, 25, 50 and 75% and with 16 Molarity. The cube specimens are immersed in sea water for 60, 90 and 180 days and tested for weight and strength variations.  The test results revealed that, there is no significant loss in weight and strength for 60 days immersion but for other immersion duration of 90 and 180 days significant variations are noticed.  From the study it is also observed that 25% replacement of Behtamcherla stone powder for GGBS is effective.
