Experimental Investigation on Reinforced Geopolymer Concrete Slabs

Abstract

Geopolymer is an ecological binding material alternative to Ordinary Portland Cement (OPC). Concrete made with this Geopolymer has several recompense compared to Ordinary Portland Cement (OPC). Generally, geopolymer concrete is the combination of Fly ash, Ground granulated blast furnace slag (GGBS), alkaline activator solution, fine aggregate and coarse aggregate. Here in this study 100% GGBS is used. GGBS is the consequence of iron and steel manufacturing industry. Alkaline solution is made up of sodium silicate and sodium hydroxide solution (NaOH) with 2.5:1. This study illustrates the experimental investigation on reinforced geopolymer concrete slabs using GGBS. The aspire is to compare the flexural behaviour of geopolymer concrete slab with the straight concrete of grade M40. The slab dimension is taken as 1000 mm × 1000 mm × 60 mm. The dissimilar molarities of NaOH used in this study are 8M, 10M, 12M, 14M and 16M.
