摘要
收缩是水泥基胶凝材料体积不稳定的一种典型现象,通过正确使用膨胀剂可以很好的起到补偿其收缩的作用。阐述了混凝土膨胀剂的膨胀源以及其应用,讨论了存在的问题及前景。
Shrinkage is one of typical phenomena of cement- based cementing material＇s volume instability. Correctly using of expansion admixture can excellently play an effect on offset shrinkage from cement- based cementing material. The component of concrete expansion admixture and solid rubbish expensive performance and application were analyzed.
