High-ductility geopolymer recycled concrete combined steel beam and preparation method thereof
The invention discloses a high-ductility geopolymer recycled concrete combined steel beam and a preparation method thereof, and belongs to the technical field of building materials, the high-ductility geopolymer recycled concrete combined steel beam comprises profile steel, high-ductility geopolymer recycled concrete is arranged in the profile steel, steel grooves are formed in the two ends of the profile steel, connecting plates are arranged on the sides, away from the profile steel, of the steel grooves, and the connecting plates are arranged on frame columns. The combined steel beam has better rigidity, the profile steel and the steel tank are welded into a whole, studs are welded inside, construction is convenient, the combination performance is better, cost is low, the building use performance is better, and compared with a concrete beam, the combined steel beam has better energy dissipation performance; the used concrete is self-made high-ductility geopolymer recycled concrete, the geopolymer concrete is subjected to toughening treatment by doping PVA fibers, and the tensile strain capacity of the material is increased by utilizing the interface bonding effect of a matrix and polyethylene fibers, so that the problem of high brittleness of the geopolymer concrete is solved.
本发明公开了一种高延性地聚物再生混凝土组合钢梁及其制备方法，属于建筑材料技术领域，包括型钢，型钢的内部设置有高延性地聚物再生混凝土，型钢的两端设置有钢槽，钢槽远离型钢的一侧设置有连接板，连接板设置在框架柱上。本发明所述的组合钢梁具有更好的刚度，将型钢与钢槽焊接于一体，且内部焊接栓钉，施工方便，组合性能更好，成本低，建筑使用性能更好，相比于混凝土梁，具有更好的耗能性能；所用混凝土为自制高延性地聚物再生混凝土，通过掺加PVA纤维对地聚物混凝土进行增韧处理，利用基体与聚乙烯纤维的界面粘结作用，材料拉伸应变能力增大，解决了地聚物混凝土高脆性的问题。
