Nano aluminum oxide modified ultra-light cement-based composite material as well as preparation method and application thereof
The invention relates to the technical field of building materials, and discloses a nano aluminum oxide modified ultra-light cement-based composite material and a preparation method and application thereof. The nano aluminum oxide modified ultra-light cement-based composite material is prepared from, by weight, 836 parts of cement and 73 parts of silica fume; 348 parts of hollow microspheres; 8.36 to 25.08 parts of nano aluminum oxide; 35 to 39 parts of steel fiber; 13 to 15 parts of a water reducing agent; 12-14 parts of a shrinkage reducing agent; and 245 to 273 parts of water. The nano aluminum oxide modified ultra-light cement-based composite material is wide in raw material source, reasonable in dosage ratio and good in feasibility of the preparation method, and the prepared nanometer aluminum oxide modified ultra-light cement-based composite material product is light in weight, high in strength, good in mechanical property and excellent in durability by adding nanometer aluminum oxide for modification. The nano aluminum oxide modified ultra-light cement-based composite material can be used for preparing ULCC plates by combining with GFRP ribs, and has the potential to become an important material for super high-rise buildings or large-span members.
本发明涉及建筑材料技术领域，公开了一种纳米氧化铝改性超轻质水泥基复合材料及其制备方法和应用，所述纳米氧化铝改性超轻质水泥基复合材料按重量份计，包括水泥836份、微硅粉73份；空心微珠348份；纳米氧化铝8.36～25.08份；钢纤维35～39份；减水剂13～15份；减缩剂12～14份；水245～273份。所述纳米氧化铝改性超轻质水泥基复合材料的原材料来源广、用量配比合理，制备方法可行性好，通过添加纳米氧化铝改性，所制得的纳米氧化铝改性超轻质水泥基复合材料产品质轻、强度高，力学性能好，耐久性优良。所述纳米氧化铝改性超轻质水泥基复合材料可用于结合GFRP筋制备ULCC板材，将有潜力成为超高层建筑或大跨度构件的重要选材。
