Improving drying shrinkage and strength development of alkali-activated high-calcium fly ash using commercial-grade calcium sulfate as expansive additive

The effect of using commercial-grade calcium sulfate (CS) in alkali-activated high-calcium fly ash (AAHFA) paste on the drying shrinkage and strength is reported. Five different fly ash (FA): CS ratios of 100:0, 97.5:2.5, 95:5, 92.5:7.5, and 90:10 were investigated. A constant Na2SiO3:10 M NaOH rati...
