| Outline of Final Research Achievements |
The bond splitting strength of low quality recycled aggregate concrete beams using vinylon fiber were studied. Compared with the case of normal aggregate concrete, the above-recycled concrete beams with vinylon fiber showed equivalent flexural cracking pattern under service loading, values of bond splitting strength at lap splices. This suggests that low quality recycled aggregate concrete could be used as a structural concrete material.
