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： Disclosed are method and system for treating concrete in mixing drums of delivery vehicles having automated rheology (e.g., slump) monitoring systems programmed to dose fluids into concrete based on the monitored rheology. The present invention takes into account a Revolution-To-Discharge value (“RTD”) which reflects drum rotations needed to move concrete towards and through the mixing drum opening from which concrete is discharged, and also takes into consideration a Volume-Per-Revolution-Upon-Discharge (“VPRUD”) value which reflects the relation between the rate of discharge and rheology (e.g., slump) of concrete upon discharge. The invention is especially useful for reclaiming concrete in the drum after delivery and can confirm rheology based upon peak (maximum) discharge pressure. The present inventors found surprisingly that discharge pressure readings are useful for recalibrating automated rheology monitoring systems as well as for reporting and/or treating the remainder concrete.

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.

摘要： The invention provides a method and system for detecting “sneak” additions of water or other fluid into the mixing drum of a concrete delivery vehicle having an automated rheology (e.g., slump) monitoring system. Sneak fluid additions are detected based on continuous rheology monitoring, even where valves and flow meters on the delivery vehicle are not used for the fluid addition. The invention is effective for monitoring additions by truck drivers who might add water from an undocumented water source (e.g., hose) along the delivery route or at the site, to hasten pouring, placement, and finishing at the time of delivery. Once sneak fluid addition is detected, the methods and system provide for reporting in the form of alerts, alarms, or other indications that sneak fluid addition has occurred, including monitor graphs or printouts confirming existence and/or extent of sneak fluid added into the vehicle mixing drum.

摘要： Disclosed are method and system for treating concrete in mixing drums of delivery vehicles having automated rheology (e.g., slump) monitoring systems programmed to dose fluids into concrete based on the monitored rheology. The present invention takes into account a Revolution-To-Discharge value (“RTD”) which reflects drum rotations needed to move concrete towards and through the mixing drum opening from which concrete is discharged, and also takes into consideration a Volume-Per-Revolution-Upon-Discharge (“VPRUD”) value which reflects the relation between the rate of discharge and rheology (e.g., slump) of concrete upon discharge. The invention is especially useful for reclaiming concrete in the drum after delivery and can confirm rheology based upon peak (maximum) discharge pressure. The present inventors found surprisingly that discharge pressure readings are useful for recalibrating automated rheology monitoring systems as well as for reporting and/or treating the remainder concrete.

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 (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.
