New Renovation Method for Jetty Structure Using High Durability Concrete Form Cured with CO₂ Gas

抄録

Studies on reduction of life cycle cost and rationalized construction methods were carried out with emphasis on the renovation of slabs of jetty structures. The results of a comparison of various kinds of renovation methods with focus on slabs of jetty structures in service revealed that a construction method using pre-cast concrete form with exceptionally enhanced durability was ideal. Analytical and experimental studies were carried out on durability design related to renovation methods, and test construction using a new renovation method was implemented. Durability was verified after the studies over the years, and a rational renovation method was proposed.
