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： The rheological probe generally has a base; an inner member fixedly connected to the base and extending away from the base, the inner member having in succession a base portion proximate to the base, and a tip away from the base, and a deformable portion located between the base portion and the tip; a shell member covering the inner member, the shell member having a proximal portion being pivotally connected to the base for pivoting about a pivot axis when subjected to a resistance pressure imparted by a relative movement of the probe in a rheological substance, and a distal portion, the distal portion being engaged with the tip, the shell member having mating features being pivotally engaged with corresponding features of the base, the mating features being located on transversally opposite sides of the proximal portion; and a deformation sensor mounted to the deformable portion.

摘要： There are described methods and systems for handling fresh concrete inside a drum . In an aspect, a method of determining calibration data for use in determining workability of fresh concrete inside a rotating drum based on hydraulic pressure is described. This method has receiving a probe pressure value indicative of pressure exerted on a rheological probe mounted inside the drum and immerged in the fresh concrete; determining a workability value indicative of workability of the fresh concrete based on the probe pressure value and on calibration data for the rheological probe; receiving a hydraulic pressure value indicative of pressure of a hydraulic fluid used for rotating the drum; and determining hydraulic calibration data by associating the hydraulic pressure value and the workability value to one another.

摘要： There is described a system generally having a rotatable drum rotatably for receiving fresh concrete, the drum having inwardly protruding blades mounted inside the drum which, when the drum is rotated in an unloading direction, force fresh concrete inside the drum towards a discharge outlet of the drum, at least one discharge outlet sensor disposed at the discharge outlet of the drum and being configured to sense the presence of fresh concrete at the discharge outlet as the drum rotates in the unloading direction; and a controller communicatively coupled with the at least one discharge outlet sensor, the controller being configured for performing the steps of: receiving a signal from the at least one discharge outlet sensor indicative of the presence of the discharged fresh concrete at the discharge outlet as the drum rotates in the unloading direction; and determining at least one parameter based on the received signal.

摘要： There is disclosed a computer-implemented method for determining a density value of a fresh concrete sample using an acoustic probe assembly. The acoustic probe assembly has an acoustic path, an acoustic emitter configured to emit an acoustic signal along the acoustic path, and an acoustic receiver configured to receive the acoustic signal after propagation along the acoustic path. The acoustic probe assembly is configured and adapted to generate an electromagnetic signal indicative of a duration of time taken by the acoustic signal to travel from the acoustic emitter to the acoustic receiver across the fresh concrete sample. The method generally has a step of determining the duration of time based on the electromagnetic signal, a step of matching the duration to a density value using reference data, and a step of displaying the density value.
