Functional Concrete Added Titanium Dioxide(TIO2) for photocatalysis was about a result strength Reduction by recent studies. Therefore, The purpose of the study is to review the possibility of TIO2 for using concrete admixture. As a result, Nano TIO2 for concrete admixture helps increased strength of concrete and here are some of the details. The compressive strength and flexural strength of cement mortar added same amount of Nano SF and TIO2 for admixture were development of strength a certain level each other. when Nano admixture use 10%, SF and TIO2 showed development of strength 60% and 40% each other gradually. If I use over 10% Both SF and TIO2, they showed irregular strength variations.
