摘要
在CGM高强无收缩灌浆料的基础上,通过改变水泥品种和添加早强剂研制出CGM抢修料。该抢修料具有1小时抗压强度超过30MPa的超早强特性,同时流动度和微膨胀性能也未改变。
A new CGM fast-aid repair material was developed by changing the kind of cement and adding hardening accelerator based on the CGM High Strength Non-Shrinkage Grouting Material.It was shown that the compressive strength of this material is 30MPa at 1h,meanwhile,the fluidity and expansion rate were not changed.
