New renovation method for jetty structure using high durability concrete form cured with CO2 gas

Abstract

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. Copyright © 2010 Japan Concrete Institute.
