Abstract:Gypsum production generates wastes in the productive chain during the extraction of the clay cap on the gypsum and in the products manufacturing. The objective of this study was to make possible the reuse of two different types of wastes from the Polo Gesseiro of Araripe in red ceramics. 5 and 10% by mass of gypsum waste was incorporated into the clay waste. The specimens were molded through uniaxial pressing and then dried at 110 ºC for 24h, sintered at 850 ºC, 950 ºC and 1050 ºC for 2h. Linear shrinkage, wat… Show more
