Abstract
Permeability performance of surface treated concrete using synthetic resin is examined experimentally. Transmission rates of oxygen, liquid phase water and vapor phase water through surface treatment-concrete system are measured. And fundamental concept of durability design against reinforcement corrosion is discussed. The conclusions in this paper are summarized as follows; (1) Transmission abilities decrease with increasing surface treatment thickness and decreasing water cement ratio. (2) While, epoxy lining or MMA impregnation is a water proofing system, silan impregnation, silan with polymer cement mortar coating or urethane lining is a water phobic system. (3) Concrete surface treatment can't elongate the service life of chloride damaged reinforced concrete member, unless chloride contaminated cover concrete is removed.
