Abstract

Construction materials mainly used Portland cement as raw materials mainly caused global warming effect around the world. This article report a review on a research work carried out on the use of geopolymer coating on the concrete surface with catalyst for a good adsorption and efficiency via photocatalytic activity using sunlight. The geopolymer paste deposited by coating on the concrete or other building construction surface. The geopolymer paste were prepared by mixing aluminosilicates material with alkaline activator added with catalyst materials such as titanium dioxide and zinc oxide. The performance of geopolymer coating in removal of dyes reported comparable with other materials. Photocatalytic activity performance evaluate by adsorption of dyes onto geopolymer.
