초록

Water repellent and waterproofing agents fail to act work properly if cracks or detachment occurs outside. The method of making mortar was tested by classifying it into two methods: direct water-repellent put in concrete and water-repellent spray to sand method. It was found that the compressive strength was decreased as the amount of water repellent was increased. As a result of measuring the contact angle, all of the specimens were hydrophobic. The spray method showed greater water repellent effect than the direct mixing method.
