EXPERIMENTS ON FLEXURE-SHEAR TEST OF COLUMNS WITH RECYCLED AGGREGATE CONCRETE : Part5 A study on RC structures used the recycled aggregate concrete

Abstract

The Purpose of this study is to grasp the possibility of using recycled aggregate concrete in the reinforced concrete structures. The seismic performance of the column members used recycled aggregate was compared with that of normal concrete members through the tests concerning flexural and shear. The parameters of the tests were three levels, of axial stress and two kinds of recycled aggregate concrete. From the test results, the failure mode can be predicted and the seismic performance of column members with recycled aggregate concrete were the same as those of the normal column members. Furthermore, it was found that the strengths of the column members with recycled aggregate concrete could be calculated as a safely side by previous strength equations.
