Due to increasing production cost and inflation in Iranian economy, gypsum production decreased during recent two years. In addition, internal gypsum demand and Iranian gypsum export have decreased in recent years. Gypsum output is classified as either calcined or uncalcined. Calcined gypsum produced domestically.
The effect of composition on the properties of calcined gypsum–lime–metakaolin pastes is investigated. The components in the calcined gypsum–lime–metakaolin–water system are found to interact synergically; there is no simple way to find the optimum composition. Therefore, an optimization is performed using the.
