Abstract: Geopolymer is an eco-friendly binding material alternative to Ordinary Portland Cement (OPC). Concrete made with this Geopolymer has several advantages 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 by-product 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 describes the experimental investigation on reinforced geopolymer concrete slabs using GGBS. The aim is to compare the flexural behaviour of geopolymer concrete slab with the conventional concrete of grade M40. The slab dimension is taken as 1000 mm × 1000 mm × 60 mm. The different molarities of NaOH used in this study are 8M, 10M, 12M, 14M and 16M. The slabs are casted and cured in ambient curing. All slabs are tested on the loading frame and load Vs deflection results are noted. The results showed that Geopolymer concrete slabs have higher strength and less deflection than the conventional concrete slab.
