Abstract: In recent years, great changes have taken place in the raw materials for concrete in Shanghai. Detection technology of concrete compression has been greatly improved and new detection technology has been continuously developed. Thus it is necessary to amend and supplement the concrete strength curve of existing standards. Using the typical raw materials of local area, the experimental work was performed on the detecting concrete compressive strength by R-value rebound method, Q-value rebound method, shear-pressure method and drilled core method. The strength curve of the above-mentioned methods and drilled core method were given by using the method of data regression. Compared with relative standard error and average relative error, the strength curve had the best effect and the highest accuracy. The strength curve was used to provide reference and suggestions for existing standards.
