Utility
System having drum discharge outlet sensors and method of characterizing fresh concrete delivery using same
23 Aug 22
The application presents 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.

Utility
Methods and system for handling fresh concrete
23 Aug 22
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.

Utility
Methods for determining fresh concrete discharge volume and discharge flow rate and system using same
18 Jan 22
There is described a method for determining a volume of fresh concrete being discharged from a drum during a discharge, the drum being rotatable and having inwardly protruding blades mounted inside the drum which, when the drum is rotated in an unloading direction, force the fresh concrete towards a discharge outlet of the drum.

Utility
Method and system for mixing concrete constituents in a drum using a probe mounted thereinside
21 Sep 21
A method for mixing concrete constituents that generally has a step of rotating a drum having a probe mounted inside the drum and immerged in the concrete constituents being mixed inside the drum; a step of receiving a first set of pressure values indicative of pressure exerted on the probe by the concrete constituents, the pressure values of the first set being taken at different circumferential positions of the probe during a single rotation of the drum; a step of determining a deviation of the pressure values of the first set from reference data; and a step of reducing a rotation speed of the drum upon determining that the deviation is lower than a threshold value.

Utility
Rheological probe
22 Jun 21
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.

Utility
System and method for determining a status of a valve using an actuator accelerometer and a reference accelerometer
9 Dec 19
The system for determining a status of a valve being mounted in a liquid supply line of a concrete mixer and being actuatable via an actuator generally has: an actuator accelerometer mounted to the actuator and being adapted to measure an actuator position associated with a position of the valve; a reference accelerometer mounted to the concrete mixer and being adapted to measure a reference position fixed relative to the concrete mixer, the actuator position and the reference position being measured while the concrete mixer is fixed relative to the ground; a computing device adapted to receive the actuator and reference positions, the computing device being adapted to determine the status of the valve based on the actuator position, the reference position and calibration position data; and to generate status of the valve indicative of the determined status of the valve.
