  • Publication number: 20240239707
    Abstract: The present invention provides a method and system for manufacturing cement wherein ground particles of cement and calcium sulfate are subjected to infrared sensors, laser sensors, or both, so that emanated, irradiated, transmitted, and/or absorbed energy having wavelengths principally within the range of 700 nanometers to 1 millimeter can be monitored and compared to stored data previously obtained from ground cement and sulfate particles and preferably correlated with stored strength, calorimetric, or other data values, such that adjustments can be made to the mill processing conditions, such as the form or amounts of calcium sulfate (e.g., gypsum, plaster, anhydride), or cement additive levels. The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.

  • Patent number: 11594305
    Abstract: 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.

  • Patent number: 10647026
    Abstract: 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 and to deploy protocols for detecting segregation. A first protocol comprises monitoring the averaged slump 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; and a second protocol comprises monitoring the instantaneous slump when the mixer drum is rotating at a constant speed for at least three successive rotations and detecting when the instantaneous slump value meets or exceeds a threshold limit. Once segregation is detected, one or more operations can be initiated, such as initiating an alarm or adjusting the mix.
