- Abstract
Polypropylene fiber (PPF) was added to concrete, and the effect of PPF on the rheological and mechanical properties of concrete was studied. The results show that with the increase of PPF content, the fluidity of concrete mixture becomes worse. Compared with those without PPF, the compressive strength, splitting tensile strength and tensioncompression ratio of concrete with PPF increase after curing for 7 d and 28 d. When the content of PPF is less than 0.9 kg/m³, the rheological properties of concrete meets the design requirements. When the content of PPF is 0.9 kg/m³, the compressive strength, splitting tensile strength and tension-compression ratio of concrete reach the maximum after curing for 7 d and 28 d.
