IStudy on high performance concrete pavement of permeability for resisting chloride ion

Liu Minghui

The test about the resistance to chloride permeability of the high performance concrete structure has been carried on in this article. The performance of the concrete resistance has been researched by the water-cement ratio, fly ash’s content and age. The results showed that with the reduction of the water-cement ratio of the concrete, the compaction degree and the permeability resistance of the concrete are higher; With the increasing dosage of fly ash, the concrete pore system and permeability resistance have been effectively improved; Finally, the concrete combination reaction is more sufficient with the longer age, and then permeability resistance is superior
