Lightweight aggregate ultra-high-performance concrete and preparation method thereof
The invention relates to the technical field of building materials, in particular to lightweight aggregate ultra-high-performance concrete and a preparation method thereof. The lightweight aggregate ultra-high-performance concrete is prepared from the following components in parts by weight: 220-400 parts of cement, 100 to 120 parts of silica fume, 5 to 150 parts of expanded pearl powder, 220 to 260 parts of expanded perlite, 15-20 parts of a water reducing agent, 76 to 93 parts of steel fiber and 130 to 160 parts of water, wherein the particle size of the expanded pearl powder is smaller than0.075 mm, and the particle size of the expanded perlite ranges from 0.075 mm to 0.6 mm. The lightweight ultra-high performance concrete designed and prepared by the invention is excellent in densityperformance, can meet the requirements of service concrete components and the like for light weight, ultra-high strength and ultra-high durability of cement-based materials in ultra-large-span bridges, super high-rise buildings, marine complex environments and the like, and has relatively high popularization value.
本发明涉及建筑材料技术领域，具体涉及一种轻骨料超高性能混凝土及其制备方法。本发明提供的轻骨料超高性能混凝土，由包括以下重量份数的组分制备得到：水泥220～400份；硅灰100～120份；膨胀珍珠粉5～150份；膨胀珍珠岩220～260份；减水剂15～20份；钢纤维76～93份；水130～160份；所述膨胀珍珠粉的粒径小于0.075mm；所述膨胀珍珠岩的粒径范围为0.075～0.6mm。本发明设计制备的轻质超高性能混凝土密度性能优异，能够满足超大跨度桥梁、超高层建筑以及海洋复杂环境下服役混凝土构件等对水泥基材料的轻质、超高强、超高耐久的要求，具有较高的推广价值。
