Abstract :

The impact performance of waste fiber recycled concrete slab is studied by ABAQUS finite element simulation. The studies show that the cracking form of waste fiber recycled concrete slabs are spread from the middle to the periphery, and the addition of waste fibers makes the stress distribution of the slabs uniform. With the increase of waste fibers incorporation, the number of recycled concrete slabs cracks is increasing when they are subjected to impact force, which indicates that the addition of waste fibers can effectively improve the impact resistance of recycled concrete. By comparing the damage patterns of recycled concrete slabs with different fibers contents, it can be observed that the incorporation of waste fibers can delay the formation and development of cracks caused by impact forces.
