A Study on Manufacture Method of Water Repellent Soil and its Water Shielding Performance

摘要

The purpose of this study is to investigate the effects of treatment methods on the impermeable ability in order to efficiently and economically make water repellent soils. The two methods of hydrophobic treatment were examined (Case I: silane treatment, and Case II: treatment by coating curing agent for concrete). Considering the characteristics of each method and the cost of production, the most efficient production method was verified. As a result of this study, it was shown that although the silane treatment can achieve the high impermeable ability, the production cost is also increased. On the other hand, in the case of the hydrophobic treatment by the coating curing agent for concrete, the production cost may be lowered, but the impermeable ability is also lowered. From the above results, it is judged that the silane treatment is more suitable as a method of manufacturing the water repellent soil by collectively evaluating the characteristics of both.
