Abstract
In this article, Control charts are employed to analyse the strength quality control of ready-mixed concrete for rigid pavement. The results of the study support that CUSUM statistical analysis is more sensitive than the Shewhart control chart. The CUSUM chart can detect the continual changes in the concrete quality in a more accurate way. By combining the CUSUM control chart and the Shewhart control chart, higher accuracy of quality control analysis could be achieved, in order words, for quality control performance when in built/pouring the ready-mix concrete as rigid pavement.
