Abstract

The DYS-2500 high temperature and high pressure rock triaxial testing machine was used to perform regular triaxial compression tests on ordinary concrete recycled aggregate concrete and recycled aggregate concrete mixed with PVA fiber. By changing the recycled coarse aggregate replacement rate of recycled aggregate concrete mixed with PVA fiber(the replacement rates, respectively, are: 0%, 30%, 60%, 100%), the performance of recycled concrete with PVA fiber was compared with conventional recycled aggregate concrete and natural aggregate concrete concerning with its mechanical properties, fracturing process, deformation as well as other characteristics of it. Studies have shown that as the replacement rate of recycled aggregate enhanced, the impact it made on its performance grows. When the replacement rate of recycled aggregate is 30%, after mixing with PVA fiber, the compressive strength of recycled aggregate concrete with PVA fiber is greatly improved, reaching 95% of the compressive strength of natural concrete. When the replacement rate of recycled aggregates is the same as the confining pressure, the peak stress of recycled aggregate concrete samples with PVA fibers is 1.12-1.36 times of ordinary recycled aggregate concrete samples.
