Gypsum can serve as a substitute for clinker in Portland Composite Cement. It affects cement's compressive strength by regulating the hydration reaction speed to optimize the compressive strength obtained. Besides, it also slows down the cement's initial hardening and the final hardening. Other materials such as trass that have not previously been considered are also used in this study. It is a soft rock or soil layer derived from volcanic ash. It is known by the name pozzolana, which can be used in cement mixtures to increase compressive strength. This research aims to observe the effect of gypsum on the quality of Portland Composite Cement, such as compressive strength, setting time and SO 3 content of mortar. They investigated clinker characteristics by adding some gypsum already done by several studies. However, the effect of SO 3 content caused by gypsum added still needs more observation.
