An Experimental Study on the Water Repellent Property of Mortar Applied Water Repellent Agent of Inorganic Polymer Type

무기질 폴리머계 흡수방지재를 도포한 모르터의 발수성능 평가에 관한 실험적 연구

Recently, Growing tendency for structure surface to use water repellent agent has increased steadily. But investigation of it's protection and durability property is not sufficient. Therefore, this paper shows the investigation about repellent property and micro structure's change in surface layer of mortar that is applied by water repellent agent. Water repellent property, absorption coefficient, air permeability, porosity and observation of micro construct was investigated according to water repellent agent type. The test results indicated that mortar applied water repellent agent appears tiny absorption coefficient, but air permeability is maintained. The reason is because silane solution is coating at capillary surface of a wall and minute pore structure is changeless.
