| Abstract |
Recently, the number of concrete structures is increasing rapidly in marine environment because it is necessary to efficiently use the limited spaces in the country. it is increasing the concern about durable performance of concrete structures in marine environment. particularly, structures in marine environment need to evaluate chloride resistance of concrete structures for durability but there is no regulation which estimates chloride resistance without destruction. Consequently in this study, Ultrasonic pulse velocity is suggested to estimate chloride resistance of concrete among non-destructive tests. As results of this study, It obtained a experimental formula from the relation between ultrasonic velocity and migration coefficient, In addition, It is possible to predict durability of concrete attacked salt damage through the method of ultrasonic velocity. |
