The Optimal Composition Range of the EVA Powder for Resistance Wheel moving Load of Cement Mortar-Type Surface Finishing Material for Parking Slab

시멘트 모르타르계 주차장 바닥 마감재의 윤하중 저항성능을 위한 EVA 분말수지의 최적 첨가 범위에 관한 실험적 연구

This study investigates the physical properties of the acrylic emulsion mortar according to variable composition set of redispersible emulsion powders. This materials have to be composed of many types of binders and chemical additives. So it is difficult to decide suitable mixing proportion of composition materials. The redispersible emulsion powders using "2, 4, 6, 8kg" of EVA polymers dispersion ranges are prepared with acrylic emulsion mortars and were tested for basic characteristics such as flexural, and compressive strength, wheel load. Through experiments we found that the improved formula to satisfy the standard of wheel load by EVA polymers, and the masration rangs between about 2.0% to 2.6% which the white portland cenmet and EVA polymers is good for resistauce wheel load.
