| Outline of Final Research Achievements |
In order to improve the durability of reinforced concrete structures, a hybrid curing agent which has both curing function and durability improvement function was developed. However, the functions, especially water-repellant function of the hybrid curing agent were not good enough. To improve the functions of the hybrid curing agent, the relationship between functions and chemical compositions of the hybrid curing agent was investigated in this research. According to results of experiments, it was fund that water-repellant function of the hybrid curing agent can be improved by mixed with alkyl tri-alkoxy silane or fluorinated polymer.
The curing function and durability improvement function of the improved hybrid curing agents were examined by the experiments, such as evaporation test, water adsorption test, accelerated alkali aggregate reaction test, accelerated carbonation test, and etc., on concrete specimens applied by the improved hybrid curing agents.
