  • We could see that, the thinner the retaining wall is, the more advantageous Premixed Agent Type Waterproof method is in the aspect of economic efficiency. The reason is because, in the case of Premixed Agent Type Waterproof method, the thicker the retaining wall is, the higher the construction cost increases due to increase in the material quantity required which increases in proportion to the area in the case of Premixed Agent Type Waterproof method. We could see that, the thinner the retaining wall is, the more inferior the economic efficiency of Infiltration Type Waterproof method is to that of Premixed Agent Type Waterproof method, as, in the case of Infiltration Type Waterproof method, the quantity of material required is fixed in proportion to the area. Consequently, we concluded that Premixed Agent Type Waterproof method is economically advantageous up to the wall thickness of 700 mm and Infiltration Type Waterproof from 800 mm.

  • Concrete with Self-healing Admixture provides waterproof protection by using a organic-inorganic chemical compound throughout the concrete. Using cement chemicals eliminate the need to use additional waterproofing, If crack is occurred, this system enhance self-healing ability to increase the structural safety. In this study, we investigate material properties to conclude mixture rate of concrete to apply a construction site.

  • In this study, comparison of setting time, compressive strength, watertightness and durability of between reference mortar with mortar using waterproof admixtures based on natural inorganic minerals. Test results shows that waterproof admixtures does not change setting time of mortar, but strongly improve compressive strength, permeability, absorption and durability of mortar. Especially early strength of mortar increased about 40% of reference.

  • This paper deals with a waterproof and mechanical feature of concrete using an inorganic self waterproof agent. The waterproof agents having been used in our country were a membrane agent, penetration agent and an organic waterproof agent. However, these agents have a lot of problems such as losing the effect of waterproof in the environment of lots of water, the difficulty of dispersion. For the clear of problems of these water -proof agents, we used the inorganic waterproof agent. This agent was made from inorganic fluosilicate. Generally, a waterproof agent has been used only for the waterproof effect. In this paper, however through the some tests of concrete using the inorganic self waterproof agent, we recognized that the concrete using the agent is more excellent in some peculiar properties than general concrete's properties. In this paper, we performed compressive strength, permeability, pore volume test, etc. As a result, the concrete of using the agent is more excellent in economy, waterproof, compressive strength.
