Abstract

"PROCESSO PARA PREPARAR SUBSTâNCIAS DE MOAGEM POZOLâNICAS OU HIDRáULICAS PARA A INDúSTRIA DE CIMENTO A PARTIR DE ESCóRIAS OXìDICAS BáSICAS". A invenção refere-se a um processo para preparar substâncias de moagem pozolânicas ou hidráulicas para a indústria de cimento a partir de escórias oxídicas básicas, especialmente escórias de aço, com aplicação de um banho de metal para reduzir óxidos de metal das escórias, a basicidade das escórias líquidas é ajustada pela adição de substâncias corretivas ácidas, tais como por exemplo, areia de quartzo e/ou escórias de alto forno e/ou substâncias corretivas contendo SiO~ 2~, antes da redução para um valor, o qual se encontra 0,1 até 0,5 abaixo do valor da basicidade (CaO/SiO~ 2~) da escória visada.
