    Gypsum is the name given to a mineral categorized as calcium sulfate mineral, and its chemical formula is calcium sulfate dihydrate, CaSO 4 ⋅ 2H 2 O. However, a broader definition includes all the calcium sulfates, including calcium sulfate hemihydrate, CaSO 4 ⋅ 0.5H 2 O, which is known as plaster or plaster of Paris (POP). Figure 6 summarizes the Experimental investigation of composite gypsum board ,These gypsum board was then tested for indoor temperature regulating performance in terms of peak temperature reduction and time delay. 2.
