Effect of Cement-based Permeable Crystallization Material on the Performance of Deterioration Concrete

摘要

During the long term service, concrete deterioration will occur due to erosion circumstance, load or unload condition, which will have negative effect on its security and durability. This article mainly discusses the effect of cement-based permeable crystallization material on compressive strength, rebound putative strength, carbonization performance, chloride permeability, and frost resistance of deterioration concrete. The result has shown that cement-based permeable crystallization material can effectively improve the strength, carbonization resistance performance and chloride resistance ability, but for the frost resistance is not obvious. We also analyze the function mechanism of the cement-based permeable crystallization material through ESEM observation.
