Abstract

"SUSPENSõES AQUOSAS DE HIDRóXIDO, USO DE SUSPENSõES AQUOSAS DE HIDRóXIDO, PROCESSO PARA O TRATAMENTO DOS CIMENTOS, USO DO CIMENTO E COMPOSIçõES DE CONCRETOS." A presente invenção trata de uma suspensão aquosa de hidróxido de pelo menos um elemento de transição selecionado e/ou de estanho, cujo potencial de oxidorredução é inferior ao do par CrO~ 4~¬ 2-¬ /Cr (OH)~ 3~(-0.12 V) que possui um pH compreendido entre 2 e 1 1, limites excluídos, para reduzir o teor de cromo VI do cimento a um valor no máximo igual a 2 ppm, que se caracteriza pelo fato de compreender de 0,5 a 80 % em peso de matéria seca de hidróxido de pelo menos um elemento de transição e/ou de estanho, em relação à quantidade de água e pelo fato de ser estabilizada por um agente de estabilização hidrossolúvel. Esta suspensão permite reduzir o teor de cromo VI dos cimentos a um valor no máximo igual a 2 ppm.
