노후화된 콘크리트 구조물 보수재료의 기초물성에 대한 연구
A Study on the Properties of the Repair materials of Concrete Structure
초록
The reinforced concrete structures have been deteriorated for various causes since it serviced for the long time. If we have to service concrete structure long time, we must repair it using appropriate methods and materials. But the data which evaluate the repair material has not been sufficient. So, the aim of this research is to estimate properties of repair materials and to acquire the data which apply to the concrete structures in field. To accomplish this objective, we have made experiment on compressive strength, bond strength, the coefficient of thermal expansion and setting time. Generally, compressive strength and bond strength are favorable but some products are unfavorable under wet curing. Setting time was faster than ordinary portland cement mortar except one material.
