摘要： A system and process for detecting dynamic segregation in concrete rotated within a mixer drum, such as mounted on a delivery truck. A system processor is programmed to monitor an instantaneous and averaged rheology parameter (e.g., instantaneous and averaged slump values) and to deploy one or more protocols for detecting the occurrence of segregation. A first protocol comprises monitoring the averaged slump or other rheology value of concrete during and immediately after a jump in drum speed of at least plus or minus four rotations per minute and detecting when a change in the averaged slump value meets or exceeds a threshold limit pre-selected by the user or the system processor; and an optional second protocol comprises monitoring the instantaneous slump or other rheology value of the concrete when the mixer drum is rotating at a constant speed for at least three successive rotations.

摘要： A gyroscopic rotational monitoring system may be utilized for monitoring one or more properties of rotatable container or vessel, and/or one or more properties of a displaceable material contained in the rotatable vessels. An exemplary aspect relates to the use of a gyroscope and periodicity sensor (e.g., accelerometer) to determine rotational speed of a concrete mixing drum, so that the slump or other property of the concrete can be monitored or adjusted such as by dosing with water, chemical admixtures, or mixture thereof.

A first protocol comprises monitoring the averaged slump or other rheology value of concrete during and immediately after a jump in drum speed of at least plus or minus four rotations per minute and detecting when a change in the averaged slump value meets or exceeds a threshold limit pre-selected by the user or the system processor; and an optional second protocol comprises monitoring the instantaneous slump or other rheology value of the concrete when the mixer drum is rotating at a constant speed for at least three (and more preferably for at least five) successive rotations and detecting when the instantaneous slump value meets or exceeds a threshold limit pre-selected by the user or processor. Preferably, both protocols are used, in any sequence, to confirm segregation within the rotating drum. Once segregation is detected, one or more operations can be initiated, such as sending an alarm or signal to the operator to confirm dynamic segregation is detected, introducing an admixture to mitigate the segregation, sending data to the batch plant for adjusting the mix design for subsequent deliveries, or other operations.

摘要： The present invention provides a method and system for detecting hardened concrete buildup in a mixer drum which is substantially devoid of plastic concrete. An exemplary method involves monitoring the hydraulic pressure required to rotate the drum through at least two successive rotations at constant speed, using a hydraulic pressure sensor on hydraulic charge side, discharge side, or preferably both sides of the hydraulic motor which turns the mixer drum; and detecting when the pressure/time data curve indicates eccentric behavior of the mixer drum, whereby an alarm or other indication is provided to confirm that the hardened concrete buildup in the truck is not acceptable. The buildup detection method and system of the present invention does not require the use of an automated slump monitoring system, but can be implemented in combination with such systems with favorable results and advantages.
