Abstract

Patente de Invenção: <B>"PROCESSO PARA APERFEIçOAR A CAPACIDADE DE MOAGEM DE SUBSTâNCIAS ADITIVAS DE CIMENTO"<D>. Para aperfeiçoar a capacidade de moagem e para ajustar as propriedades hidráulicas de aditivos para a moagem de cimento, especialmente escórias, cinzas volantes ou puzolanas, os aditivos para a moagem de cimento são submetidos antes do processo de moagem a um tratamento de temperatura entre 250°C e 1000°C (figura 3).Invention Patent: <B> "PROCESS TO IMPROVE THE GRINDING CAPACITY OF ADDITIVE CEMENT SUBSTANCES" <D>. To improve the grinding capacity and to adjust the hydraulic properties of additives for grinding cement, especially slags, fly ash or puzolans, additives for cement grinding are subjected to a temperature treatment between 250 ° before the grinding process. C and 1000 ° C (figure 3).
