gypsum rock in civil engineering

Review of gypsum reinforced composites as building materials
2024.4.16 Gypsum, a pivotal building material, is formed by heating gypsum rock to eliminate its naturally occurring crystallization water, a technique utilized since ancient times. By subjecting calcium sulfate dehydrate (CaSO 4 ⋅2H 2 O) from gypsum rock to varying temperatures, partial or complete dehydration occurs [ 3 , 4 , 5 ].
