- Abstract
Primary concrete with pebble coarse aggregate was used as the source of recycled pebble, all or part of natural pebble was replaced with recycled pebble to prepare concrete. 99 specimens were designed with different replacement rate. The prism compressive strength, cube compressive strength? flexural strength, elastic modulus and Poisson's ratios of specimens were tested. The failure pattern, stress-strain curves, peak stress, peak strain, elastic modulus and Poisson's ratios of specimens were determined. Based on the test data, the conversion relationship of various strength indexes was proposed. The research results show that comparing with natural pebble concrete, the strength of recycled pebble concrete slightly increases? in different replacement ratio, the stress-strain curves of recycled pebble concrete are steeper than those of natural pebble concrete at descending section, the elastic modulus, deformation performance are lower than those of natural pebble concrete, but Poisson's ratio is close.
