Utilização de escória de alto forno e cimento Portland com adição de plastificante sintético e plastificante natural (Argila) para fabricação de solo-cimento

Abstract

In this work we used steel slag and Portland cement CP II F-32 for the manufacture of soil cement in eight different formulations. For purposes of analysis of physical and mechanical properties it was made specimens with compositions equivalent to 97, 95, 93 and 90% of cement additions in granulated blast furnace slag. Since the blast furnace slag is formed during a slow cooling process, its components form different crystalline phases that do not allow them to acquire properties of hydraulic binders, it was necessary to test two plasticizers, plasticizer of synthetic origin and Clay, plasticizer natural origin. Parameters such as chemical composition of raw material, water absorption and apparent density for samples with curing time of 21 and 28 days and compressive strength for samples aged longitudinal healing 15, 21, 28 and 40 days.
