The method involves measur- previous ing energy at a first drum speed and a second drum I speed. Slump is calculated using low speed en- I ergy/speed/slump curve data, or pre-stored equa- tion wherein slump is derived as a function of slope of the line. The energy, speed, slump rela- • • • • • • . • • • • . tionship in the provided concrete is compared to at least two data drum pre-stored curves across speed ranges of 15 0.5 RPM - 6 RPM and 6 RPM - 20 RPM, to ascertain whether the provided concrete ..-1 matches any of the stored curve data; either activ - • ating the monitoring system for all drum speed ; is the ranges where a match confirmed or allowing monitoring system to calculate slump only at low drum speeds. 1-1 .4t time 1-1 1-1 Drum speed Mix 2 pressure IC - - 01 — — — — Mix 1 pressure • • Slump 01 0 FIG.1 It - - 1-1 0 ei O
