Study On The High Durabilities Of High Performance Concrete For Ocean Construction With Expansive Agent

In this thesis, the influences of combinations of slag and expansive agent at different rations on the mechanical properties and durability of high performance Concrete for ocean construction were studied. Under the fluctuation of water-binder ration, quantum of slag and expansive agent, corrosion solutions, the variable laws of compressive strength, flexural strength, change of length and weight and chloride permeability were discussed. According to the study, high performance Concrete for ocean construction should have the ability of resistance solutions corrosion, and decrease the change of length.The results indicated that: 1) Reduce the water-binder ration can improve strength and the ability of resistance solutions corrosion, and decrease the change of length and weight; Reduce the water-binder ration can effectively increase the chloride-penetration resistance. 2) Slag added to HPC can improve the ability of resistance solutions corrosion, with more slag can better improve the ability of resistance solutions corrosion; The...
