This study has made a multiple regression analysis using data resuils of various concrete testings and data from the construction sites of the expressways.
Then we have clarified the relationship between compressive strength (Y) and condition of material, mix proportion, etc. (X1, X2, …, Xn).
Furtheremore, we propose the concrete quality control system by which the compressive strength of concrete can be calculate by use of the multiple regression expression instead of strength tests as follows; Y=A+B1X1+B2X2+…+BnXn
where, A, B1, B2, …Bn: constant
