HYBRID ULTRA-HIGH PERFORMANCE ENGINEERED CEMENTITOUS COMPOSITES INCORPORATING STEEL AND POLYETHYLENE POLYMER FIBERS: AN EXPERIMENTAL STUDY

摘要：

　　A hybrid ultra-high performance engineered cementitious composites (HUHP-ECC) with steel (ST)and polyethylene (PE) fibers was developed in present study.The volumes of ST and PE fiber were adjusted to obtain the different mechanical properties, including the compressive strength and tensile properties.It is found that the tensile strength increased with the amount of PE fiber, while the compressive strength had the opposite tendency with the two fibers volumes.The flowablity of HUHP-ECC was improved with the increasing amount of ST fiber.Finally, the morphology of PE and steel fiber at fracture surface was observed by environmental Scanning electron microscope(ESEM).
