Method for strengthening cold-formed thin-walled steel column based on geopolymer foam concrete
The invention discloses a method for strengthening a cold-formed thin-walled steel column based on geopolymer foam concrete. The method specifically comprises the steps of using cold-formed thin-walled steel for building a column base body in a surrounding mode, uniformly stirring the slag powder and the fly ash, then adding the construction waste powder, and stirring to obtain a powder base material, adding an alkali activator and water into a concrete mixer, stirring, sequentially adding polypropylene staple fibers, a powder base material and a foaming agent, and stirring in batches to obtain geopolymer foam concrete slurry, pouring the geopolymer foam concrete slurry into the column base body, standing and foaming, and curing to obtain the geopolymer foam concrete reinforced cold-formed thin-walled steel column. The cold-formed thin-walled steel-geopolymer foam concrete column is adopted as a novel combined component in the light steel and light concrete combined structure, good sound insulation and noise reduction performance can be achieved, the empty drum sound of an existing light steel structure can be eliminated, and the requirement of the national building sound insulation standard can be met.
本发明公开了一种基于地聚合物泡沫混凝土强化冷弯薄壁钢柱的方法，具体包括：利用冷弯薄壁钢构建围接成柱体基体；将矿渣粉、粉煤灰搅拌均匀，然后再加入建筑垃圾粉末搅拌得到粉末基料；在混凝土搅拌机中加入碱激发剂、水进行搅拌，再依次加入聚丙烯短纤维、粉末基料、发泡剂进行分批次搅拌得到地聚合物泡沫混凝土浆料；将地聚合物泡沫混凝土浆料浇筑在柱体基体内；静停发泡；养护后得到地聚合物泡沫混凝土强化冷弯薄壁钢柱；本发明采用冷弯薄壁型钢－地聚合物泡沫混凝土柱作为轻钢轻质混凝土组合结构中的一种新的组合构件，能够达到良好的隔声降噪性能，能够消除现有轻钢结构的空鼓声，能够满足国家建筑隔声标准的要求。
