| Outline of Final Research Achievements |
In the present, recycled aggregate attain the practical level as a recycled material. So, case study of using recycled aggregate is increased to use for the building structure. However, recycled aggregate has some issues to prevail using as building structures. The purpose of this study is to improve strength and suppress drying shrinkage and creep property by mixing fly ash in concrete with recycled aggregate. As a result, the compressive strength and drying shrinkage were improved by using blast furnace slag. The compressive strength and drying shrinkage were evaluated by pore volume of under the 2μm. By mixing fly ash, creep coefficient of concrete with recycled aggregate could be suppressed more than ordinary concrete.
