Anti-abrasion ultra-high performance concrete
The invention belongs to the field of building materials, and particularly relates to abrasion-resistant ultra-high performance concrete. Waste composite material broken particles are subjected to surface modification and shaping, waste composite material particle aggregate for concrete is prepared, the aggregate is used for preparing the abrasion-resistant ultra-high-performance concrete, and raw materials comprise cement, fly ash microspheres, silica fume, the composite material broken particle aggregate, steel fibers, synthetic fibers, a water reducing agent, an expanding agent and water. The water cement ratio is 0.16 to 0.18. The concrete has excellent working performance, mechanical performance, crack resistance and abrasion resistance, and can be used for water flow erosion and debris flow impact parts such as ship locks, galleries, dams, piers and the like of hydraulic structures. Meanwhile, the invention develops a new method for recycling the waste composite material, and has important significance on solid waste recycling and environmental protection.
本发明属于建筑材料领域，具体涉及一种抗冲磨超高性能混凝土。本发明将废弃复合材料破碎颗粒表面改性整形，制备得到混凝土用废弃复合材料颗粒集料，采用该集料制备出抗冲磨超高性能混凝土，原材料包括水泥、粉煤灰微珠、硅灰、复合材料破碎颗粒集料、钢纤维、合成纤维、减水剂、膨胀剂和水，水灰比为0.16‑0.18。具有优异的工作性能、力学性能、抗裂性和抗冲磨性能，可用于水工结构船闸、廊道、大坝、桥墩等受水流冲刷和泥石流冲击部位。同时，本发明开辟了废弃复合材料回收利用的新方法，对固废资源化和环境保护具有重要意义。
