This study is analyzed about the factor of adhesive strength characteristics, curing time, asphalt application, test temperature which are liquid waterproofing membrane of rubber-asphalt and chloroprene-rubber type for concrete bridge deck. According to the results, curing time is shorter, adhesive strength is less in chloroprene-rubber type. And also chloroprene-rubber and rubber-asphalt type are showed high adhesive strength in low temperature.

The problem of water leakage due to damaging waterproof in concrete structure, causes the impediment in a long term and shortened the life span of durability. There are a lot of techniques for repair and reinforcement to improve using environment. However, the improper construction which is unconsidered various environmental conditions, could effect to increase the maintenance expenses. Therefore, this study will be compared and estimated the adhesion liquid and sheet integrate waterproofing material, as analyzing the existing problem. For those result, we would like to arrange the alterative plan for the long durability and user needs of concrete structure.

Seat waterproofing materials applied to the roof of a building concrete structure inevitably produce joints and are applied with opposite dam joints or overlapping joints depending on the waterproof material applied to the top of the sheet. In this case, the joint performance is determined by the material at the top, rather than by the superimposed joint. In order to solve this problem, various reinforcements have been used to apply to the connecting parts of the opposite dam, but the problem of attachment between different materials or the lack of reinforcement of the joint tape has not been solved. Therefore, for the purpose of securing tensile performance to the joints, this study is used as a reinforcement for the joints of PP materials with high tensile performance and as a reinforcement for nylon materials.

본 연구에서는 수평 탈기반 시스템을 대상으로 구성부재에 대한 물리적 특성과 결합재인 노출 및 비노출형 시멘트 혼입 폴리머계의 배합비에 따른 실험적 성능을 평가하기 위해 관련규정에 따라 해당시험을 실시하였다. 실험 결과 수평 탈기반의 구성부재는 기본적인 물리적 성능을 확보함을 확인하였고 결합재로 사용되는 노출 및 비노출형 시멘트 혼입 폴리머계 방수재료의 배합비에 따른 실험적 성능을 평가하였으며 이를 토대로 최적 배합비를 도출하였다. 연구 결과는 향후 건설현장에서 수평 탈기반 시스템을 적용하는데 유효한 기초자료로 활용될 것으로 판단된다.

A general bentonite mate waterproofing material applied salt pollution without particular way(it is a land reclaimed from a sea(or near by sea). Analysis showed that it(general bentonite mate) has a little resistant salt pollution and a little watertightness. There are a lot of problem before completed structure because of salt pollution. So that, they have to a sum of money to repair works. Also, to repaired a part leak water again and again. because it doesn't match for salt pollution. So, I am going to study about a bentonite mate waterproofing material in salt pollution and it will be within the range of possibility to underground structure under the salt pollution. Also, I suggest waterproofing method in salt pollution about workability, stability, economy and etc.

This study deals with the characterizing and the application like as insulation materials in the joint part in concrete surface layer and waterproofing sheet especially for roof slabs. Using steel materials and butil-rubber tape to band waterproofing sheet and concrete surface together before this waterproofing system will be applied. It can be expected to both the curability and the watertightness by coating poly-urethane 2 or 3 times with sheet surface. Therefore this waterproofing system can be possible to protect water without the damage when vapor is going out from concrete and without air pockets because of the difference temperature inside and out. This system particularly consists of air bents and elastic waterproofing sheet considering the physical damage while water can cause purely physical damage. This system is one of the most efficient ways of waterproofing system without air pocket.

Urethane waterproofing materials which currently being used most commonly in the Korean domestic market have high applicability and construct layers without forming any joints, but under the influence of low temperature and low humidity, as well as the thickness of the applied layer, the curing time of this material may become extended in construction sites. To resolve these issues, a proposed method of using water-hardening type of polyurethane waterproofing materials are being developed. However, there currently lacks any standards or evaluation methods on determining an optimal mixture ratio of water for the water-hardening polyurethane waterproofing materials. Therefore, for the establishment of a board applicability of the water-hardening polyurethane waterproofing methods in construction sites, this study objectively analyzes the changes in the performance of these materials depending on the changes of the water mixture ratio and attempts to procure the optimal ratio on the basis of forming a provisionary standard.
