Abstract

PEçAS DE GESSO DE ALTA RESISTêNCIA E MéTODO DE OBTENçãO DE TAIS PEçAS refere-se á formação de peças de gesso (sulfato de cálcio dihidratado) com alta resistência mecânica obtida com o auxílio de películas de água com espessura nanométrica. Utiliza-se sulfato de cálcio, tanto do dihidrato como do hemihidrato, para se obter peças desses dois materiais puros ou misturados, especialmente para uso na construção civil, preparadas diretamente por intermédio da prensagem de seus pós levemente umedecidos.
