Environment-friendly sleeve grouting material for steel bar connection
The invention relates to the technical field of sleeve grouting materials, in particular to an environment-friendly sleeve grouting material for steel bar connection, which comprises a gel system mixture, and the gel system mixture is formed by mixing water glass and urea. Compared with the prior art, the environment-friendly sleeve grouting material has the beneficial effects that the gel system mixture formed by mixing the water glass and the urea is doped into the sleeve grouting material, so that the grouting material has an early-strength and high-strength mechanism, the hardened slurry has early-strength and high-strength performance, and the structure becomes compact along with age development, and the fluidity is better. And secondly, due to the fact that the organic silica gel does not have the shrinkage characteristic of polyacrylamide polymers in oil, an oil layer can be seriously blocked due to improper construction of the system, the pollution to the environment is small, and the material is very environment-friendly.
本发明涉及套筒灌浆料技术领域，尤其为一种环保钢筋连接用套筒灌浆料，包括凝胶体系混合物，所述凝胶体系混合物由水玻璃和尿素混合而成，与现有技术相比，本发明的有益效果是：本发明通过在套筒灌浆料中掺入由水玻璃和尿素混合而成的凝胶体系混合物，使得灌浆料具有早强高强机理,硬化后浆体具有早强高强性能,随着龄期发展结构变得较为致密。且流动性较佳，其次，由于这种有机硅胶并不具有聚丙烯酰胺类聚合物在油中的收缩特征,因此该体系施工不当会造成油层严重堵塞,对环境污染小，十分环保。
