Characteristics of Cement Mortar using Water Repellent with Controlled Surface Structure to Imitate Ecology

생태모방 표면구조 제어에 의한 발수제 혼입 시멘트 모르타르 특성

compared and reviewed the water repellency and strength characteristics by controlling the surface stamping size and fine aggregate ratio of cement mortar mixed with water repellent as a method to control the ecological imitation surface structure. As a result of measuring the contact angle, the higher the ratio of fine aggregate, the larger the contact angle. The contact angle increased when the surface structure was changed by stamping, and increased as the stamping size became smaller. In the surface stamping of mesh#150, the contact angle was particularly increased.
