Abstract
This study presented the effect of 0−5wt% TiO2 addition on compressive strength and thermal shock resistance of fly ash based geopolymer composites, which were prepared by activating high calcium fly ash reinforced with basalt fibers. The compressive strength of the composites after aging 28days increased to 52MPa when 5wt% TiO2 was added. The retained compressive strength as 5wt% TiO2 was added after 15 thermal cycles (800°C) was 26MPa, which was increased by 44% compared to TiO2 free composites. Such an enhancement was ascribed to the acceleration of hydration reactions in geopolymer structures resulting more C−H−S phases which resulted in a denser matrix with increased strength.
