A Non-linear analysis of Wall Putty and ConcreteCubes for Self-Cleaning usingTitanium Dioxide

Abstract

Concrete is the most common construction materials for building construction. However, in urban region the surface of concrete is contaminated due to air pollution.  Self-cleaning construction materials have the ability to clean themselves by breaking down and removing dirt, pollutants, and other contaminants without the need for human intervention. Photocatalytic materials such as titania (TiO2) and zinc oxide (ZnOgenerally possess self- cleaning properties in it and is introduced in this study. This paper reviews the Non-linear analysis ofTitania and Zinc oxide on concrete and wall putty. The optimum dosage of Titania is investigated and the its periodic absorption is noticed to check the removal of dirt from the surface of concrete. The same principle is applied on wall putty panel. The results of the study showed that TiO2 can be used upto 10%. Increase in dosage decreased the tensile strength of finished putty layer.
