Abstract
This research presents the comparative study using FGD gypsum (FGD) and calcium sulfate (CaSO4) on mechanical properties and drying shrinkage of alkali-activated high-calcium fly ash (FA) mortar. FA was replaced by FGD and Ca2SO4 at the rates of 5.0% and 2.5% by weight of binder, respectively. This ratio of FDG and Ca2SO4 was based on the previous study in term of low drying shrinkage of alkali-activated high-calcium FA paste. Sodium silicate (Na2SiO3) solution and 10M sodium hydroxide (NaOH) solution were used as liquid alkaline activation in all mixtures. Test results found that the use of FGD and Ca2SO4 to replace FA resulted in decreasing of setting time whereas its strength development improved. However, at the later stage, the compressive and flexural strengths of alkali-activated high-calcium FA with Ca2SO4 decreased. The use of FGD and Ca2SO4 in alkali-activated high-calcium FA mortar decreased its drying shrinkage, in which comparison with the control mix.
