Description

The purpose of this study is making the performance of the recycled aggregate using the aggregate test result of the recycled aggregate into an indicator. And the last purpose of this study is modifying to the recycled aggregate concrete with which are satisfied of the performance demanded with the indicator of the recycled aggregate. It tries to predict estimate Carbonation and Drying shrinkage of the concrete which mixed recycled aggregate using the indicator of recycled aggregate from the result of an experiment in the first half of this paper. The method for modifying to the mix design of the recycled aggregate concrete which has the strength demanded using the prediction equation obtained from the result of the compression test of the concrete in the second half is shown.
