Since the existed research has n't illuminated the failure form of post-embedded reinforcing steel bar bonding anchor and its mechanism, has n't systematic research on factors influencing the function of post-embedded reinforcing steel bar bonding anchor, and also failed to test on the long period validity of post-embedded reinforcing steel bar bonding anchor, it is very unfavorable for the spread and application of post-embedding technique . in the meantime, the fact that the present post-embedding anchoring material is of few kinds, high prices and still-to-be-improved performance has become the bottleneck of the post-embedding technique's development, which has restricted its further application and development . therefore, it is of great importance to develop a new type high-performance inorganic anchoring material with reasonable price and improved performance 由于已有研究对后植钢筋粘结锚固的失效形式、破坏机理未作出明确回答,对后植钢筋粘结锚固性能的影响因素未进行系统研究,对后植钢筋粘结锚固的长期有效性未予以试验证实,不利于植筋技术这种新型结构加固技术的推广应用,同时现有植筋锚固材料存在品种少、价格高、性能需要进一步改进和提高等局限性,已成为植筋技术发展的瓶颈,制约了植筋技术的进一步应用和发展,因此开发价格合理、性能优良的新型高性能无机质类锚固材料就显得尤为重要和迫切。
