摘要:

This paper studied the impact resistance of high zirconium alkali-resistant glass fiber reinforced full-scale concrete slabs from the perspective of dynamics by the drop hammer test, and compared with macro-polypropylene and steel fiber. The effects of fiber type and fiber volume fractions on the impact resistance of concrete slabs were investigated, the concrete slab acceleration and the support reaction force time-history curve were measured, and the dynamic test results and failure mode of specimens were comparative analysis. All fiber reinforced concrete slabs show ductility failure, as the increase in fiber volume fractions, the impact resistance of specimens was improved more significantly, and the impact resistance of slabs exhibits secondary strengthening properties and experienced elastic-plastic phase. When the volume fraction was 0.45%, the first impact resistance of macro-polypropylene fiber and glass fiber reinforced concrete slab was similar, while when the volume fraction was 0.75%, the impact resistance of macro-polypropylene fiber reinforced concrete slab was better. With the same volume fraction, the second impact resistance of macro-polypropylene fiber reinforced concrete slab was better than that of glass fiber. Although the impact toughness and energy dissipation performance of high zirconium alkali-resistant glass fiber reinforced concrete compared with other fiber is not outstanding, but the comprehensive analysis shows that it has advantages in the use of the corrosion environment.
