英文摘要The attempt to replace concrete aggregates and oil well cement additives with waste tires accumulated year by year is considered sustainable and waste recycling. Notably, introducing fiber material can eliminate the deterioration effect of waste tire rubber on the mechanical performance of rubberized cement material. However, the mechanical strength and deformation properties of rubberized cement sheath barrier reinforced with inorganic hybrid fibers has not attracted much attention. This study focused on the mechanical behavior of rubberized cement sheath barrier reinforced with inorganic hybrid fibers. The uniaxial compressive strength of the cubic cement samples increased gradually with the increase of curing time and the cement stone samples maintained the structural integrity after compressive testing. Triaxial compressive strength test results showed that the cement with the waste tire rubber, SBR latex and inorganic hybrid fiber showed good ductility characteristics from the stress-strain curves, and the energy-based ductility indexes were enhanced by 37.9%-64.6%. In addition, it was found that the low elastic modulus of the samples coupled with a large single cycle loading strain resulted in a large dissipation energy and strain. The three aspects of space skeleton, crystal dislocation and slippage, and bridging effect of fibers can be used to elucidate the mechanism of increasing deformation capacity. The results of SEM-EDX and XRD analysis showed that the inorganic hybrid fibers of different sizes randomly distributed in the rubberized cement matrix, and the composition of the cement slurry was improved. This study is intended to provide reference for improving the mechanical integrity of rubberized cement sheath barrier under multiple cyclic loading/unloading conditions.
