Keywords:Steel concrete composite structures, Steel form, waterproofing performance, reactive adhesive waterproof material

The purpose of this study is to verify the waterproof performance of the steel-concrete composite structures using reactive adhesive waterproof material. The waterproofing tests were conducted with mock-up specimens of the composite wall set the steel form on outer surface. In the case of without waterproof material, easily the colored water passed through the interface when the gap was existed under steel form. In the case of with waterproof materials, the water leakage was not observed. Furthermore, using normal water-swelling rubber, tiny water leakage was observed after removing the steel form, using the reactive adhesive waterproof material the water leakage was not occurred at all.
