摘要
系统介绍了镁质抗裂剂的性能及其工程应用情况。镁质抗裂剂由轻烧氧化镁辅以部分功能调节材料制备而成,可根据工程需要调节膨胀性能。养护温度对镁质抗裂剂性能影响较大,养护温度越高,体积膨胀稳定期越短。工程应用表明,镁质抗裂剂的使用能有效控制混凝土裂缝,实现混凝土结构自防水。
The article has a systematic introduction on the performance and engineering application of magnesian anti- cracking agent. The agent is made from light calcined magnesia along with some function adjusting materials, and the expansion performance can be adjusted as per engineering requirement. Curing temperature has a great influence on the property of the agent. The higher the curing temperature is, the shorter the volume expansion stable period will be. Engineering application show the use of magnesian anti-cracking agent can effectively control cracks on concrete, and realize concrete structure self waterproofing.
