Abstract


This paper presents an investigation into the performance of alkali-activated slag (AAS) mortar exposed to elevated temperatures. Sodium silicate, sodium hydroxide and a mix (waterglass) with a modulus (SiO2/Na20) of 1.5 were used as activators. The specimens were heated in an electric furnace up to 1000 ºC in steps of 200 ºC for a constant period of 2 hours. The weight loss, residual compressive strength, resistance to chloride ion penetration, porosity and capillary sorption were evaluated and the results were compared with those of ordinary and blended Portland cement mortar
