In this study, natural and synthetic gypsum have been used as sulfate activator. The artificial phosphogypsum was used in two different ways such as original and calcined form in the mixtures. Class C fly ash and lime content were used as 50%, 70%, 90% and 50%, 30%, 10% respectively while the gypsum content was constant as 10% in all the mixtures. Samples were cured by keeping the air and steam cure. All mixtures were subjected to spreading test. The compressive strength of the samples was performed at 4, 7 and 28 days. The compressive strength results obtained from the tests have shown that calcined phosphogypsum and steam curing have better results in terms of gypsum type and curing condition
