PROCESSO APERFEICOADO PARA FABRICAR CONCRETO QUE TEM ALTA RESISTENCIA A CORROSAO;COMPOSICAO DE CIMENTO E ADITIVO PARA FAZER CONCRETO

摘要

Concrete having high resistance to corrosion is prepared by using low aluminate (C3A) cement, preferably having less than 5 weight per cent of aluminate, and, in addition to conventional concrete constituents, at least 10 weight per cent of finely divided, reactive silica based on the cement weight.
