Abstract

A manufacturing method of a grouting material for a building wall includes the steps: firstly, uniformly mixing, by weight, 5-10 parts of dodecylamine, 2-3 parts of glutamic acid, 1-1.5 parts of alkylglycoside and 35-40 parts of n-butyl alcohol; placing mixture into an autoclave; pressurizing the autoclave to reach 0.15-0.25MPa; controlling temperature to range from 80 DEG C to 90 DEG C; keepingconstant pressure and constant temperature for 15-30 minutes; adding 4-8 parts of methyl oleate after reducing the pressure and the temperature; pressurizing the autoclave again to reach 0.2-0.3MPa; keeping the temperature increased to 100-110 DEG C for 10-20 minutes; dropping 2-3 parts of mixed liquid of oleic alcohol polyoxyethylene ether and isooctyl alcohol after reducing the pressure and thetemperature. By adding anti-shrinking agents, a solidified body of the grouting material cannot shrink after hydration reaction of the grouting material, the anti-shrinking agents can be uniformly distributed in the solidified body under the action of anti-settling agents, local shrinkage of the solidified body is avoided, and the service life of the wall is ensured.

Description

technical field [0001] The invention relates to a method for manufacturing a grouting material for building walls, and belongs to the technical field of building walls. Background technique [0002] The grouting material is mainly used for building reinforcement, enlarging the section of beams and columns, thickening the wall structure and repairing leakage and seepage, grouting for the collapse of various foundation projects and various emergency repair projects, etc. After reinforcement, the strength, stiffness, crack resistance, stability and durability of the structure should meet the requirements. In the prior art, the grouting material will shrink during the curing process, which makes the target volume of the required grouting body different, and it takes a certain time to solidify during grouting so that the solid fillers and additives will settle, and this settlement The phenomenon leads to unstable performance of the grouting material, and it is more prone to shri...
