Abstract
- The present research aims to explain the physico-chemical and mechanical characteristics of alkali activated slag geopolymer binder (AASGB). Commercial sodium hydroxide (SH) and sodium silicate liquid (SSL) are utilized as an alkaline activator at different temperature namely 25oC and 65oC. The hydration characteristics and physico-mechanical properties are illustrated through the determination of combined water contents Wn), combined slag, total porosity (TP), compressive strength (CS), bulk density (BD) and XRD analysis as spectroscopic tools upto 180 days. The durability of the AASGB against aggressive ions (sulphate and chloride ions ) as well as effect of elevated temperatures upto 1000oC are studied. The activated binders are immersed under 5% MgSO4 and/or 5%MgCl2 solutions upto12 months. The data showed that the higher concentration of SH (1mol/kg) at 65oC exhibited the highest resistance to elevated temperature upto 1000oC as well as given a high resistance against sulphate and chloride attack.
