Abstract:
In order to improve the fatigue performance of recycled aggregate concrete(RAC), basalt fiber was incorporated to make basalt fiber reinforced recycled aggregate concrete(BFRAC). The bending fatigue performance of BFRAC with different fiber volume fractions was investigated, then the fatigue deformation law of BFRAC was analyzed, and the effect of fiber volume fraction and stress level on its fatigue life was studied by response surface methodology(RSM). The results show that the fatigue strain and fatigue modulus of BFRAC develop in three stages. With the increase of stress level and cycle ratio, the fatigue strain gradually increases and the fatigue modulus gradually decreases. With the increase of fiber volume fraction, the development of fatigue strain and fatigue modulus slows down, and the effect is the best when the fiber volume fraction is 0.3%. The fatigue life of RAC is lower than that of normal aggregate concrete(NAC)at the same stress level, and the incorporation of basalt fibers can significantly improve the fatigue life of RAC, with the increase of fiber volume fraction, BFRAC fatigue life shows a trend of increasing first and then decreasing. The fatigue life prediction model of BFRAC established by RSM is tested and proved to have good accuracy. The interaction of fiber volume fraction and stress level has some effect on BFRAC fatigue life, but the magnitude of stress level has more significant effect on BFRAC fatigue life. The multi-objective optimization of BFRAC using the desirability function shows that optimal fiber volume fraction is 0.321%, 0.317%, and 0.313% at 0.6, 0.7, and 0.8 stress levels, respectively.
