Effect of Catalytic Crystalline Waterproof Coatings on Steel Reinforcement Corrosion of Concrete

Abstract:

Article Preview

Catalytic crystalline waterproof coatings (CCWC) can penetrate into pores and cracks of concrete and catalyze reaction to increase the impermeability of concrete. This paper reported the results of a study conducted to evaluate the effect of CCWC on corrosion of concrete. The test results of water impermeability, chloride permeability and potential clearly showed that CCWC could stop water and any soluble salts from penetrating the concrete to cause corrosion. Moreover, results of the secondary impermeability test and SEM micrographs indicated that the active compound could work for a longer term and endow the cement-based materials with self-healing function, which make concrete more compacted. Therefore, it was concluded that CCWC is very effective to protect the steel from corrosion in concrete.
