Influence of Alkali Concentration on Strength Characteristic of GGBS Based Geopolymer Mortar
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 4
Abstract
The use of alternative non-cementing materials as cement replacement material can overcome the environmental issues, especially the global warming problem caused by the emission of greenhouse gases due to the manufacturing of cement in huge amounts. It was estimated that the amount of Carbon dioxide emitted during the process of cement production was equivalent to 1 ton for each 1 ton of cement. However, the major problem of the non-cementing material like Ground Granulated Blast Furnace Slag, a waste byproduct of steel industry is to activate with the help of alkali-activators so as to proceed for polymeric chain reactions. The most commonly used alkali-activators are the combination of sodium hydroxide (NaOH) and sodium silicate at fixed concentration. The present study is an attempt to study the effect of variation of concentration of sodium hydroxide on setting and strength characteristic of GGBS based geopolymer mortar with molarity variations of 4M,6M,8M,10M,12M and 14M, the compressive strength test was performed after 1,3,7,14 & 28 days of ambient curing . The results revealed that the highest compressive strength was achieved by geopolymer mortar at an optimum molar concentration of 12M. It exhibits a higher strength to that normal mortar at 28 days. However, the use of NaOH molarity more than 12M tends to decrease the strength of non-cement geopolymer mortar specimens.
