The purpose of this experimental study is to develop the waterborne silicon acrylic surface finishing material of parking lots. Adhesion strength experiment was conducted in order to enhance performance of the finishing material by adopting modified polyamide resin. The results qualified the standard regarding bond strength which is prescribed in KS F 4937. They are confirmed that the strength tend to increase as the amount of polyamide increased and could be an optimum surface finishing material applicable for parking lot floor.

The purpose of this experimental study is to carry out test for the surface finishing material of parking lot using Cross-linking agent(Zinc Oxide). The specimen was fabricated by KS F 4937, Cross-linking agent 2%, 3%, 4% is mixed in water soluble acrylic resin. As a result, bond strength of surface finishing material using Zinc oxide 4% was confirmed to be superior than surface finishing material using ordinary Acrylic resin.

Reinforced concrete is used as a main construction because it is excellent durability and strength. However, the problem of durability decrease due to enlargement, high-rise of structures and the cracking due to external force nowadays. Therefore, there is studying on the Textile Reinforced Concrete(TRC), which reinforcing bar changing into Textile. Also, studying on adhesion performance between concrete and Textile. Preceding studies have examined the adhesion performance of single fibers with no specific variable. It can not reflect about grid type and embedding length. Accordingly, on this study examines the change of bond strength according to bond length. As a result, the bond strength increased as the embedding length of the Textile increased, but there was not influence that the bond strength according to the lateral length.

This paper describes the evaluate adhesion area effects on structural performance of structural sealants. In this experimental, glass panel thickness and initial construction depth of sealant are 12 and 5mm. Principle variable is addition of sealants : 5, 10, 15mm. Prior to add sealant, adhesion part carried out cover with primer. Test method is based on the bending test. Loading method is to put sand on the center of the glass panel in order to the wind load applied to the actual condition. Test results indicated that addition of sealants is not improve the peak load.
