Abstract

Study the effect of using commercial red iron oxides as concrete admixtures in percentage do not exceed 2.5% of each oxide from the amount of cement. This study tested the effect of every portion from the each oxide at different ages on the compressive strength as well as the workability represented as values of slump. We conclude that the optimum portion of RIO 2.5% is coloring material & mineral admixture, through the compressive strength increased as 5.5-12.8%. Iron oxide classified as coloring materials admixture in addition it improves some mechanical properties. Partial replacement of cement (up to 40%)with GGBS admixtures to improve high strength of concrete and 2.5% replacement of iron oxide to improve the workability and increase the slump & coloring of concrete. The river sand with full replacement (100%) of M-sand. The GGBS admixtures using different level of concrete is 25%,30%,35%,40%.The iron oxide admixtures using different level of concrete is 1%,1.5%,2%,2.5%. The maximum strength of concrete is by 40% of GGBS & 2.5% of iron oxide replacement of concrete.
