| 要旨 | The effect of recycled aggregate quality on the variation of compressive strength was examined at several water-cement ratios. The variation of recycled aggregate concrete strength was higher than that for normal aggregates but still fell below the JSCE-specified limit, except when combining different recycled aggregate types. An index factor integrating mix proportion and aggregate properties was then proposed to estimate strength and a high degree of correlation was shown both for the experimental results as well as past research results including fly ash concrete. |
