Abstract

Abstract

According to the changes in five parameters，such as the replacement ratio，reinforcement ratio，the content of baked brick aggregate，the content of silicon powder and the content of multivariate mixed fiber，the 13 EC-RAC beam specimens were designed to carry out bending performance tests． The test results show that in the various factors，the reinforcement ratio significantly influences the flexural bearing capacity of the bending beams; with the increase of replacement ratio，on the one hand，the bending bearing capacity is not decreased but increased． On the other hand，the compound action of the silicon powder，the hybrid fiber and the active mineral material can effectively improve the flexural performance; the proper brick grain content with its characteristics of strong water imbibitions due to its macrospore，which indirectly reduces the water-cement ratio in the RAC，to a certain extent， also improves the bending performance．
- various factors,
- recycled concrete beam,
- bending performance,
- bearing capacity
