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： Described are a method and system for minimizing errors in the manufacture or management of aggregate-containing construction materials such as concrete. Aggregates used for making concrete are stored or weighed in dry bulk bin type hoppers, and conveyed from these hoppers into mixer drums which batching or mix the concrete. The hoppers or conveyor belts may contain sensor probes for measuring moisture levels in the aggregate. These sensor probes require calibration from time to time, but time and expense are required for proper calibration, leading to habitually erroneous moisture level data used in the industry on a daily basis. The present inventors believe that the smallest inaccuracies in aggregate moisture level readings can have profound effects on the properties of the resultant concrete product. To confront this long suffered problem, the present inventors surprisingly discovered that the inaccuracy of these aggregate moisture sensors, as used for evaluating the aggregate as a dry bulk material, can be detected and even addressed through the use of slump monitoring systems to evaluate the concrete slurry mix prepared from the aggregates.

摘要： Disclosed are dosing methods for mitigating the deleterious effect of clays, which are born or conveyed by sand aggregates, crushed rock, gravel, and other aggregates used in the manufacture of concrete, upon the dosage efficiency of cement dispersants added into concrete. Instead of introducing the entire clay mitigation agent (CMA) into the aggregate material before or during batching in the cement batch plant in a singular, upfront dose, the present invention comprises administering CMA doses on at least two instances in a rotatable truck-mounted mixer drum, wherein at least 21%-100% of the total CMA added into the concrete is added after initial batching of water, cement binder, and clay-bearing aggregates in the rotatable truck-mounted mixer drum during the transit portion of the delivery between initial batching at the cement batch plant and the pour event at the job site.

摘要： Described are a method and system for initiating a majority percentage of chemical admixture dosage into a delivered concrete load preferably just before arrival of the concrete delivery truck at the delivery pour site, such that a maximized slump (or slump flow, or other slump characteristic) increase occurs just before discharge/pour. The invention employs a concrete slump management system having a processor that is programed to consider time of pour (discharge) and stored data that includes dosage response (change of slump characteristic) of the concrete mix due to past additions in the same type of concrete mix, and thus maximizes pre-pour increase in slump characteristic while minimizing or avoiding the risk of overshooting the slump target as well as limiting the time required for adjusting concrete to attain the target slump value at the jobsite.

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.

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.
