Comparative Study and Evaluation of the Compressive Strength and Mechanical Wear Resistance of Colored Geopolymer Concrete Based On Slag as a Binder

Abstract

The goal of this study is to compare the compressive strength and mechanical abrasion resistance of colored geopolymer concrete based on slag as a base ingredient. Three percentages of three colored oxides from slag were considered: 1%, 2%, and 3% of red iron oxide, green chromium oxide, and yellow iron hydroxide. In addition to a little amount of water, the combination contains a high plasticizer. According to the study's findings, the compressive strength and abrasion resistance performed best when the proportion of addition was 1% for the red and yellow colors and 2% for the green color, which generated the best results and mechanical wear resistance aluminum oxide.
