Abstract

The invention relates to a preparation method of a high-temperature-resistant inorganic planted bar anchoring material, and belongs to the technical field of anchoring materials. According to the method, saline-alkali soil is extracted, extract liquid of the saline-alkali soil is collected, a lot of alkaline water solution dissolved in the extract liquid of the saline-alkali soil, blast furnace slag, coal ash and the like are excited to form a gelling material, residual water is removed by hydrated alumina silicate and C-S-H gel in the gelling material in a high-temperature environment, akermanite is grown in a high-temperature environment, gelling properties of the gelling material are effectively improved at high temperature, and the high-temperature resistance of the material is effectively improved. The anchoring material is heated by glutinous rice, internal starch of the anchoring material is gelatinized and compounded with sodium polyacrylate to form thickening agents, carbonation reaction is performed in the high-temperature environment, the thickening agents are glued into the inside of the material, a gap of carrying fracture of the material caused by high temperature iseffectively filled into a micro-pore, the anchoring effects of the material are further improved in the high-temperature environment, and the high-temperature resistance of the inorganic planted bar anchoring material is improved.

Description

technical field [0001] The invention relates to a preparation method of a high-temperature-resistant inorganic rebar anchoring material, which belongs to the technical field of anchoring materials. Background technique [0002] In the reconstruction, reinforcement and reinforcement projects caused by the addition of floors, plane changes, function changes or structural quality defects, the connection problems between the original steel bars and the newly added steel bars in the buildings are often encountered. In the past, many projects were The concrete protective layer of the original building is chiseled out to expose the original steel bars, and then the new steel bars are welded and connected with the original steel bars to ensure the joint force. Although this method is reliable, the construction is complicated and the original There is some damage to the building. As a new reinforcement and maintenance technology, planting bar technology has its unique technical adva...
