| Abstract: | Through the work performance, cube compression, split tensile and elastic modulus tests, the change law of high strength polypropylene coarse fiber reinforced recycled aggregate concrete (HFRAC) with the increase of HPP fibers (high performance polypropylene fibers) content under different aggregate replacement ratios was studied. And compared with corrugated steel fiber reinforced recycled aggregate concrete (SFRAC). The results show that the working performance of HFRAC gradually decreases with the increase of fiber content, similar to SFRAC, but the decline rate gradually decreases with the increase of fiber content; The cubic compressive strength of HFRAC does not change significantly with the increase of fiber content, but the elastic modulus decreases slightly; The split tensile strength of HFRAC increases gradually with the increase of fiber content, and the tensile-compressive ratio gradually increases, and the plastic properties are better than SFRAC. In addition, it was found that as the replacement rate of recycled aggregates increased, the mechanical properties of HFRAC and SFRAC decreased. |
