摘　　要：用硅酸盐水泥和耐热增强材料研制开发的耐热植筋胶在极限使用温度分别为小于等于300℃和600℃的2个等级下,热力学性能技术指标稳定、可靠,达到了我国耐热混凝土规范技术要求;耐热植筋胶的锚固抗拔力实验结果也满足我国《混凝土结构后锚固技术规程》JG J145—2004规定,耐热植筋胶可以长期在600℃以下高温环境中工作,不怕电气焊等施工作业,是冶金、电力、化工及建材等行业混凝土结构加固、技术改造必备材料.The heat resisting anchoring adhesive is developed with portland cement and heat-resistant reinforced material, which has stable and reliable thermodynamic property at the level of≤300℃, or ℃ 600℃ and meets the technical regulation of heat resisting concrete. The anchoring strength also meets the technical regulation of concrete construction after anchorage （JGJ145-2004）. This adhesive can work properly for long time at 600℃ and doesn＇t fear electric weld. The heat resisting anchoring adhesive is a necessary material in the industry of metallurgy, electric power, chemistry and building material as the concrete reinfocement and technical innovation.
