Experimental Study on Permeability Resistant and Pore Structure of High Content Mineral Admixtures of HPC

Abstract:

The influence of water absorption and chloride permeability for high content mineral admixtures HPC with W/B ratio and curing age have been tested, pore structure of concrete have been tested by mercury intrusion method (MIP) and the relationship with permeability resistance also have been analyzed. The research show that chloride ion penetration resistance and water absorption decreased significantly with the extension of curing age and low W/B ratio. Marine engineering high-performance concrete with double adding fly ash and blast furnace slag has excellent resistance to chloride ion permeability. The pore structure of concrete can optimize by double adding and the pore distribution are more reasonable.
