Effect of molar content on GGBS based geopolymer pervious concrete

Abstract

GGBS based Geopolymer pervious concrete (G-GPC) with different molar ratio M8, M10 and M12 studied in this research work. Geopolymer concrete normal fly ash used but in this study GGBS is used, for maintaining the previous property in G-GPC without fine aggregate, 12mm size coarse aggregate utilized in this work, Alkaline solution (sodium silicate NaoH and sodium hydroxide Na2Sio3). Alkaline liquid to solid ratio 0.45. Ratio between Sodium silicate and sodium hydroxide is 2.5. The casted concrete kept in ambient curing. The specimens are attending compression test, Split tension test, Water absorption test, density tests are conducted in the specimen. The Experimental results are analyzed by ANNOVA analysis Method and compare the results of compression test split tension test water absorption test. Based on the above study M12R2.5 G-GPC is perform well when compared to other two molar ratio.
