Green ultra-high performance concrete with ultra-high fracture toughness, high strength and large fluidity and preparation method of green ultra-high performance concrete
The invention discloses green ultrahigh-performance concrete with ultrahigh fracture toughness, high strength and large fluidity and a preparation method of the green ultrahigh-performance concrete, and belongs to the technical field of ultrahigh-performance concrete. The alkali-activated concrete is used as a base material, and the modified sisal fibers and the modified graphene-PE fibers are doped, so that the green ultra-high performance concrete with ultrahigh fracture toughness, high strength and large fluidity, which has the advantages of high fracture toughness and mechanical strength, high setting speed, good fluidity, relatively high construction performance and durability and the like, is obtained; the method can be widely applied to bridge engineering and road engineering. The desulfurized fly ash, coal gangue and other industrial wastes are used as raw materials, the problems of industrial waste stacking and the like can be solved, waste is turned into wealth, resources are saved, and the environment is protected.
本发明公开了一种超高断裂韧性、高强、大流动性绿色超高性能混凝土及其制备方法，属于超高性能混凝土技术领域。本发明以碱激发混凝土作为基材，通过内掺改性剑麻纤维和改性石墨烯‑PE纤维，得到了具有断裂韧性和力学强度高、凝结速度快、流动性好、施工性能和耐久性能较高等优点的超高断裂韧性、高强、大流动性绿色超高性能混凝土，能广泛应用于桥梁工程和道路工程。本发明以脱硫灰、煤矸石等工业废弃物为原料，可以解决工业废弃物堆放等问题，变废为宝，并且节约资源，保护环境。
