This study investigated the strength of concrete to improve construction material with polymer cement mortar. Some mixtures composed of Ethylrne Vinyl Acetate(EVA) and Acryl were studied. The two mixtures carried out the physical, mechanical test to determine its properties which a include : compressive, flexural, bond strength test. The test results show that the compressive strength was increased at long-term age when compared to early ages for increasing polymer contents. It was found that flexural strength and bond strength became larger as polymer to cement ratio became higher.

Recently, High clean water System is growing rapidly. When concrete of High Clean Water System become antioxidant due to ozon for High Clean Water, It has problem that durability is declined. The study develop Ozone Resistance Paints to prevent corrosion of the concrete and a performance was evaluated. Experimental result ascertain resistance about ozon and some acids. The study is expected that durability of concrete about High Clean Water System by using Ozone Resistance Paints improvement.

In Marine environment reinforced concrete structures, such as intake structure, water and chloride ion penetrated into concrete through the cracks of concrete and its permeable property, cause the corrosion of reinforcing steel bar, which accelerates the expansive cracks and deterioration of concrete. The purpose of this paper is to evaluate on deterioration of durability concrete through instrumental analysis such as schmidt hammer and chloride content. Under the reclaimed marine environment, the main cause of deterioration of concrete structures is the steel corrosion due to the penetration of chlorides and the deterioration of outer concrete itself by chemical attack.
