(1 School of Civil Engineering, Tianjin University, Tianjin 300072, China; 2 National Center for Quality Supervision and Test of Building Engineering, Beijing 100013, China)Abstract: Experiments were done on mortar with the methods of column compression and point load, and then to compare the conversion intensity and the standard compressive strength. The principle ofleast squares method and five kinds of function form were adopted to regression analysis of data in order to be a function. Comparison of two detection methods intensity was set up links to reduce the detection error by detecting the intensity into a standard compressive strength.
Keywords: pointload method; mortar strength; function
