摘要： A mixer vehicle includes a mixer drum, a first acceleration sensor, a second acceleration sensor, and a controller. The first acceleration sensor is configured to produce first acceleration signals and the second acceleration sensor is configured to measure accelerations within the mixer drum to produce second acceleration signals. The controller is configured to receive the first acceleration signals from the first acceleration sensor and second acceleration signals from the second acceleration sensor. The controller is further configured to determine a presence of material within the mixer drum based on the first acceleration signals and the second acceleration signals. The controller is further configured to determine one or more properties of the material within the mixer drum based on the first acceleration signals and the second acceleration signals.

摘要： Process and system for managing a mix design catalog of a concrete producer that involves collecting slump curve data obtained during in-transit monitoring of delivered concrete loads made from a plurality of various mix designs, wherein each mix design is identified by a different identification code (regardless of whether components are different), clustering slump curve data having same movement characteristics according to assigned strength value, and selecting a mix design to produce, to display, or both to produce and to display, from among the two or more slump data curves of individual mix designs within the same data curve cluster. The selection is based on same movement characteristic and assigned strength value, and at least one factor relative to cost, performance, physical aspect, quality, or other characteristic of the concrete mix or its components. Exemplary methods for generating new mix designs are also set forth.

摘要： The invention relates to a computer-aided method and a device for controlling a concrete mixing plant for the production of ready-mixed concrete (1) or mixed concrete, which is mixed at least from the components cement (6a; 6b) and aggregates (8a, 8b, 8c) with the addition of water (9) in a motor-driven mixer unit (3), wherein at least the required mixing time (tM) of the mixer unit (3) is calculated before the start of the mixing process by means of an electronic prognosis unit (10), which calculates the current moisture (F), measured by means of at least one moisture sensor (11), of at least the aggregates (8a, 8b, 8c) to be added and the temperature measured by means of at least one temperature sensor (12;13;14) or thermal imaging camera, in order to determine the required mixing time (tM) of the mixer unit (3) on the basis of a predetermined concrete formulation (18), taking into account the various measured values determined by the sensors.

摘要： The method of handling fresh concrete generally includes the steps of receiving a viscosity value of the fresh concrete and a pressure value of a pressure exerted on a Theological probe moving in the fresh concrete; using a processor, accessing at least two calibration data sets, the at least two calibration data sets including combinations of different reference pressure values and associated reference workability values for a corresponding one of at least two reference viscosity values; determining a viscosity difference value by comparing the received viscosity value to the at least two reference viscosity values; and determining a workability value of the workability of the fresh concrete based on the reference workability values associated with reference pressure values corresponding to the received pressure value in the at least two calibration data sets and on the viscosity difference value; and handling the fresh concrete based on the determined workability value.

摘要： 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： Aspects involve estimating transitions in properties of a concrete mixture prior to batching and during transport of the mixture from a first location, such as a concrete batch plant, to a second location, such as a job site and controlling a mixture of ingredients for concrete in response. A tool may execute a method for estimating an initial temperature at batching and a change in temperature of the concrete mixture during transport due to the exothermic reaction of the mixture, percentages and types of ingredients of the mixture, and/or environmental factors along a transit route. A control system at the concrete batching plant may control one or more components of the concrete batch plant in response to the estimated temperature change, such as a dispenser of an ingredient of the mixture and/or a heating or cooling mechanism to adjust the temperature of an ingredient of the concrete mixture.

摘要： Method and system to measure and monitor the grey water content in a rotating concrete mixer drum mixer truck using a sensor attached to the interior of the concrete mixer drum. By measuring the grey water content before a batching process takes place, the batched water (and cement content and admixture type and content) can be modified in order to maintain expected performance of the batched load in terms of both strength and rheology, or more simply, some or all of the grey water can be discharged from the concrete mixer drum before batching.
