  • Patent number: 11224989
    Abstract: 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. The method generally has discharging a volume of the fresh concrete from the drum by rotating the drum in the unloading direction for a given number of discharge rotations; obtaining discharge flow rate variation data indicative of a discharge flow rate varying as function of discharge rotations; and determining a discharged volume value indicative of the volume of fresh concrete being discharged from the drum of the mixer truck during said discharge based on the given number of discharge rotations and on the discharge flow rate variation data.

  • Patent number: 8764272
    Abstract: The invention provides ‘thixotropy’ monitoring, by measuring the reversible, time-dependent reduction in viscosity occurring when concrete is subjected to mixing, and employs a mixing drum and conventional slump monitoring equipment as used on ready-mix trucks. In one embodiment, the drum is rotated until concrete is completely mixed; the speed is altered, such as by increasing it to a predetermined level; and the energy required to rotate the drum (ER) is monitored; the maximum (ER-MAX) and minimum (ER-MIN) values are recorded in computer memory; and these values are compared to pre-determined (target) values. Rheology factors (including viscosity, yield stress, and/or thixotropy) can be adjusted accordingly by adding liquid component(s) into the mix. This method, suitable for delivery of highly fluid concrete speed such as SCC, can involve transit and placement rheology targets during monitoring.

  • Publication number: 20140104972
    Abstract: 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.

  • Patent number: 7374331
    Abstract: A method and apparatus for reducing the viscosity of a fluidic cementitious mixture, the apparatus including a high voltage source, first and second spaced electrode members electrically connected to the high voltage source and (when energized) define an electrostatic field therebetween. The positioning of particulate cementitious material within the electrostatic field imparts like charges to the cementitious particles. By establishing such an electric field and positioning cementitious particles within the field, the particles may be charged prior to mixing into a hydrated cementitious slurry. Such charging decreases the viscosity and/or enhances the flowability of the hydrated cementitious slurry.

  • Publication number: 20080084783
    Abstract: Methods and systems for controlling processes related to the amount of fluid in a container subjected to externally-excited motions. Fluid level sensor measurements in processing tanks on-board boats are confused by ocean waves and swells. A hydrodynamic model of a fluid in a tank can be constructed using non-linear dynamic model algorithms with inputs such as multi-axis accelerations, fluid viscosity, and apparent level measurements. The model can be used to filter-out boat motion disturbances to obtain a corrected level of the fluid in the tank. The corrected fluid level signal can be further processed using a dynamic model of the tank and associated input and output flow rates in a closed loop observer. The methods and systems are especially advantageous for offshore equipment such as cementing and fracturing ships.

  • Publication number: 20080025138
    Abstract: A stand holds a bag of dry mortar mix while a user pours measured quantities therefrom to prepare a mortar admix in a mixing container. The stand has a base with folding legs which elevates the bag to approximately the level of the top of the mixing container. A platform, or elevator, hingedly coupled to the front of the base holds the dry mortar bag while a user tilts the elevator and bag for pouring. A chute on the platform channels the dry mortar into the container as needed while the user stirs it with water to prepare the mortar admix. The elevator includes a handle opposite the hinge for manipulating the bag. A vertical spine atop the elevator near the handle slips under a flap on the end of the bag to hold it erect and in place while pouring. The device includes one or more latches which hold the elevator and legs in their folded positions adjacent the base for transportation and storage.

  • Patent number: 6923565
    Abstract: A process and equipment for producing multi-color concrete products, including architectural concrete blocks, concrete bricks, modular concrete products that are suitable for use in landscaping applications, such as retaining wall blocks, concrete pavers, and concrete slabs. The invention includes a hopper that is divided into separate sections, with each section intended to contain a differently colored concrete. Each hopper section includes a controllable discharge opening that permits precise control of the amount of each concrete color that is discharged from the hopper. The colored concrete is then transported to and dumped into a hopper of a concrete product production machine, where the concrete is blended into a multi-color concrete blend for use in producing the concrete products.
