Outline of Final Research Achievements

Recycling technology of structures was studied. In this study, the fly ash from a thermal power station and the recycled aggregate from concrete flake were used. Three examinations were carried out in the purpose of knowing the basic performance of concrete which used the fly ash and the recycled aggregate. Firstly, the durability was confirmed for knowing about deterioration progress of the concrete. Secondly, the mechanical property by using the recycled aggregate was confirmed. Thirdly, the numerical analysis method was established for designing of actual structure.
