Abstract:
ABSTRACT The purpose of the present study is to investigate the behaviour of Fly ash based Geopolymer eco Bricks and its Durability, the size of the bricks were adopted was 190mmx90mmx90mm. The brick were cast with fly ash to river sand and eco-sand (silica sand) with the Different ratio’s of 1:1.6, 1:1.8, 1:2 by weight. The optimum water/ binder ratio of 0.416 was selected as per available literature. The water/binder ratio is the ratio of solution ( NaOH and water) to fly ash. Bricks will be casted in this study under ambient curing. Visual inspection of Geopolymer mortar samples did not reveal any recognizable change in colour and remained structurally intact though the exposed surface turned slightly softer. Through Optical microscope, corroded surface could be seen which increased with time of exposure. After exposure in the acid solution for 18 weeks, the Geopolymer samples almost lost its alkalinity and showed very low weight loss in the range from 0.54% to 0.28% of initial weight. Loss of weight was found higher for specimen with higher percent of Na 2 SIO3. Results obtained in the present study indicate that Geopolymers are highly resistant to sulfuric acid.
