Porous metal lightweight ultra-high performance concrete composite material and preparation method thereof
The invention discloses a porous metal lightweight ultra-high performance concrete composite material and a preparation method thereof, and the porous metal lightweight ultra-high performance concrete composite material comprises porous metal A which is cut into a preset shape to serve as an integral framework, granular porous metal B and lightweight ultra-high performance concrete slurry C, the lightweight ultra-high performance concrete slurry C comprises a cementing material, a pre-wetted lightweight aggregate, fibers, water, a water reducing agent and a functional additive, the cementing material comprises the following components in percentage by mass: 40-60% of cement, 15-25% of silica fume, 10-20% of lightweight floating beads and 15-30% of hollow microspheres, and the sum of the mass percentages of the cement, the silica fume, the lightweight floating beads and the hollow microspheres is 100%. The compressive strength of the composite material composed of the light ultra-high performance concrete and the porous metal is improved to a certain degree, the limit strain of the composite material is improved by more than one time, and the energy absorption efficiency of the composite material is remarkably improved when the composite material is used for an anti-collision structure.
本发明公开了一种多孔金属轻质超高性能混凝土复合材料及其制备方法，多孔金属轻质超高性能混凝土复合材料包括切割成预设形状作为整体骨架的多孔金属A、颗粒状的多孔金属B和轻质超高性能混凝土浆体C，所述轻质超高性能混凝土浆体C包括胶凝材料和预湿轻骨料、纤维、水、减水剂、功能外加剂，所述胶凝材料包括按质量百分比计的水泥40～60％、硅灰15～25％、轻质漂珠10～20％、空心微珠15～30％，所述水泥、硅灰、轻质漂珠、空心微珠的质量百分比之和为100％。本发明轻质超高性能混凝土与多孔金属组成的复合材料抗压强度有一定程度的提升，且其极限应变提升1倍以上，将其用于防撞结构时其吸能效率显著提升。
