Abstract: At present，there are no test methods for detecting compressive strength of non-standard concrete hollow block in Chinese Code． Through the study of American Product Standard and combing with the characteristics of product types in China，it was presented an experiment on cutting method for detecting compressive strength of nonstandard concrete hollow block，and finally it was also given the intensity conversion relationship between the detected strength of specimen for non-standard concrete hollow block and the strength of standard block，which had reference value for perfecting the Chinese block inspection standard．
