Study of some properties of colored geopolymer concrete consisting of slag

Abstract

In this study, the possibility of producing colored geopolymer concrete consisting of slag as a binder and studying the effect of pigment on some properties of geopolymer concrete is discussed. Here two types of pigments (chromium oxide “green” and iron oxide hydroxide “yellow”) were added to the geopolymer concrete and some tests such as slump values, compressive strength, flexural strength, and permeability test were conducted. The results showed that the best percentage of pigment addition was 1% of the weight of the slag, and with increasing addition, the mechanical properties began to deteriorate.
