Ultra-light high-strength geopolymer-based composite material and preparation method thereof
The invention relates to the technical field of building materials, and discloses an ultra-light high-strength geopolymer-based composite material and a preparation method thereof.The ultra-light high-strength geopolymer-based composite material comprises a cementing material, hollow microspheres, an exciting agent and polyethylene fibers, and the cementing material comprises granulated blast-furnace slag and silica fume; the exciting agent comprises water, sodium silicate or a mixture of sodium silicate and sodium carbonate. According to the invention, sodium silicate or a mixture of sodium silicate and sodium carbonate is used as an exciting agent, and the sodium silicate modulus of the exciting agent is 1.2-1.6, so that the product has higher early-stage compressive strength. Meanwhile, the hollow microspheres are used as light micro aggregate, so that the composite material has the properties of light weight, high strength and the like, and the polyethylene fiber can improve the defects of low tensile strength, poor toughness and the like of a common geopolymer matrix, and has the effects of crack resistance and toughening; and construction and development of structures such as super high-rise buildings, large-span buildings and offshore platforms can be promoted.
本发明涉及建筑材料技术领域，公开了一种超轻质高强地聚物基复合材料及其制备方法，所述超轻质高强地聚物基复合材料包括：胶凝材料、空心微珠、激发剂、聚乙烯纤维，所述胶凝材料包括：粒化高炉矿渣和微硅粉；所述激发剂包括：水、硅酸钠或硅酸钠与碳酸钠的混合物。本发明采用硅酸钠或硅酸钠与碳酸钠的混合物作为激发剂，激发剂的硅酸钠模数为1.2～1.6，使得产品具有更高早期间抗压强度。同时，本发明以空心微珠作为轻质微集料，使复合材料具有轻质、高强度等性能，聚乙烯纤维可以改善普通的地聚物基体存在的抗拉强度低、韧性差等缺陷，起到阻裂、增韧的作用，有利于促进超高层建筑、大跨度建筑、海上平台等结构的建设与发展。
