Introduction In mechanical and material engineering, the cracking of brittle films attached to substrates is a well-known phenomenon.
Fractures in layered materials have been intensely investigated in the past decades for it is important to civil engineers, mechanical engineers and geoscientists [1].

Properties of Phosphate Cement Mortar Used as Rapid-Repair Material Deng Hongwei a, Yang Yingzi,b and Gao Xiaojian c School of Civil Engineering, Harbin Institute of Technology, Harbin 150001, China adenghw200305@yahoo.com.cn, byzyang@hit.edu.cn, cxjgao2002@yahoo.com.cn Key words: magnesium phosphate binder (MPB), rapid-repair material, mechanical properties, shrinkage Abstract.
The fracture surface is not completely through the MPB-concrete interface, but it partly passes through the original mortar, which illustrates that MPB binder system and the traditional cement-based materials have good compatibility and can meet requirements of repairing engineering.
MPB mortar-this new binder material system has good compatibility with traditional cementitious material and is suitable to rapid repair of concrete engineering.
