Abstract
Method and system for monitoring slump flow of hydratable cementitious material such as wet concrete in a rotating mixing drum. Whereas prior art methods use a single value of the hydraulic pressure for turning the drum (such as the average value) and correlating with slump values using the vertical drop measurements of the standard slump test (e.g. ASTM C 143-05), the present invention involves analysis of values corresponding to slump flow of concrete samples, preferably having slump flow values of 16-36 inches when measured using standard slump flow tests (e.g., ASTM C1611-05).
