Abstract

CONTROLE DE COR E RECUPERAÇÃO DE CALOR NA PRODUÇÃO DE ARGILA ATIVADA. A invenção refere-se a um método para produzir um material cimentício suplementar para uso em um produto de cimento ou concreto, sendo que o método compreende as etapas de ativar argila ao material cimentício suplementar entre 600 e 1000 graus Celsius; tratar o material cimentício suplementar ativado sob condições reduzidas para formar um produto reduzido e resfriar o produto reduzido a 300-400 graus Celsius por um processo de arrefecimento brusco sob condições oxidantes.
