柔性纤维水泥砼冲击性能研究

目前,国内对于砼类材料冲击性能的评价尚未有统一的标准.本文运用摆锤冲击法和落重弯折冲击测试方法对柔性纤维砼、普通砼的冲击性能进行了对比实验研究.实验结果表明:和普通水泥砼相比,柔性纤维砼具有优良的抗冲击能力,柔性纤维砼在路面中运用可以增强路面抵抗行车荷载的冲击和振动,使路面具有更加优良的动力服务性能.

The study on impact performance of flexible fibers concrete

There is not uniform criterion to study the impact performance of concrete materials nowadays. In order to investigate the performance of flexible fibers concrete, pendulum-hammer impact experiment and fall-weight impact experiment were carried out in laboratory. The experimental results show that flexible fibers concrete has more excellent impact performance than traditional concrete, and the application of flexible fibers concrete in pavement can improve the pavement capacity to resist the impact and vibration of vehicles and can improve the pavement service.
