摘　　要：北京市某城楼及城台修缮工程中,在保护古建筑原状的基础上选用现代高性能抹灰材料,与传统抹灰材料相比,该材料具有更好的冻融循环粘结强度、微柔初性、低收缩率和良性的耐久粗性,采用现代工艺方法,解决了基层平整度差异大、含水率较高、附着力差等问题。In the renovation project of a tower and city platform in Beijing,modern high-performance plastering materials were selected on the basis of protecting the original state of ancient buildings.Compared with traditional plastering materials,this material has better freeze-thaw cycle bonding strength and micro-flexibility.With high performance,low shrinkage rate and benign durability,modem technology is used to solve the problems of large differences in the flatness of the base layer,high moisture content,and poor adhesion.
