Method for reinforcing T-shaped beam by using regenerated geopolymer mortar
The invention provides a method for reinforcing a T-shaped beam by using regenerated geopolymer mortar. Comprising a T-shaped beam, an FPR grid, an interface agent and regenerated geopolymer mortar. The FRP grid is adhered to the web of the concrete beam by using an adhesion agent, and geopolymer mortar is sprayed on the surface of the FRP grid to form a web reinforcing system. Compared with the prior art, the characteristics that the FRP grid is simple in construction and high in strength, and the geopolymer mortar is fireproof, resistant to high temperature, good in durability, capable of setting early, beneficial to crack self-healing and the like are fully utilized, T-shaped beam web cracks caused by loads, environments and other factors can be effectively repaired, the bending bearing capacity and the shear bearing capacity of the T-shaped beam are improved, crack development is delayed, and the service life of the T-shaped beam is prolonged. And the durability of the T-shaped beam is improved.
本发明提供一种采用再生地聚物砂浆加固T型梁的方法。包括T型梁、FPR网格、界面剂、再生地聚物砂浆组成。本发明在混凝土梁腹板处使用界面剂粘贴FRP网格，在其表面喷涂地聚物砂浆形成腹板加固体系。相比现有技术，充分利用FRP网格施工简单、强度高及地聚物砂浆防火、耐高温、耐久性好、早凝、有利于裂缝自愈合等特点，可有效修复因荷载、环境等因素造成的T型梁腹板裂缝，并提高T型梁的抗弯承载力和抗剪承载力，延缓了裂缝开展，增加T型梁的耐久性。
