Ultra-high performance concrete as well as preparation method and application thereof
The invention provides ultra-high performance concrete as well as a preparation method and application thereof, and particularly relates to the technical field of concrete. The ultra-high performance concrete is prepared from an inorganic cementing material, sand, gamma-phase aluminum oxide, graphene slurry, composite fibers and water, wherein the composite fibers comprise steel fibers and polyformaldehyde fibers. The ultrahigh-performance concrete provided by the invention has excellent high-temperature resistance, the residual compressive strength is almost not lost after the ultrahigh-performance concrete acts at the high temperature of 600 DEG C, the residual compressive strength is only lost by about 50% after the ultrahigh-performance concrete acts at the high temperature of 1000 DEG C, and the ultrahigh-performance concrete is suitable for special scenes with relatively high requirements on the high-temperature resistance of materials.
本发明提供了一种超高性能混凝土及制备方法和应用，具体涉及混凝土技术领域。该超高性能混凝土包括无机胶凝材料、砂、γ相氧化铝、石墨烯浆料、复合纤维和水；其中，复合纤维包括钢纤维和聚甲醛纤维。本发明提供的超高性能混凝土具有优异的耐高温性能，在600℃高温作用后的残余抗压强度几乎无损失，1000℃高温作用后的残余抗压强度仅损失约50％，适用于对材料耐高温性能有较高要求的特殊场景。
