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.

Abstract: Disclosed is a method for determining volume of a concrete mix load in a mixer drum based on use of an in-and-out sensor probe which submerges into and exits from the concrete during drum rotation and which provides data to a processor used for calculating volume based on the data. To provide for concavity, convexity, and/or cascading surface flow effects that can hinder accurate determination of the concrete load volume, the processor may be configured to compare original batch volume and/or rheology of the concrete load monitored during drum rotation. The calibration of load volume value, highly useful for monitoring or admixture dosing purposes, can be done based on comparison of real-time data with historic data gathered over time and stored in processor-accessible memory. Further exemplary embodiments also take into account the speed and/or tilt of the drum (due to roadway conditions), concrete mix design, and other factors.

Abstract: This invention relates to apparatus and method for measurement and monitoring of physical properties of materials, such as liquids, and more particularly to acoustic instruments, methods, and systems that automatically measure air content in real-time within liquids, including concrete, mortar, or other hydratable cementitious mix suspensions using resonant electroacoustic transducers that have their radiating surfaces in contact with the liquid.

Abstract: A nozzle, including a support member and a nozzle boot surrounding at least a portion of the support member, the nozzle boot having a nozzle boot inlet and a nozzle boot outlet spaced from the nozzle boot inlet and a volume between the nozzle boot inlet and the nozzle boot outlet, the nozzle boot being expandable upon the introduction of fluid into the volume, and collapsible upon withdrawal of fluid from the volume. Also disclosed is a method of removing unwanted concrete from a surface by creating tensile stress to concrete adhered to that surface by causing the surface to expand, and a system for injecting fluid (s) into a rotating drum.

Abstract: Volume of a concrete mix load in a rotatable mixer drum is determined using an in-and-out sensor probe system wherein the probe submerges into and exits from the concrete during mixer drum rotation and provides data to a processor used in the system for calculating volume of the concrete mix load based on the data. To take into consideration any concavity, convexity, and/or cascading surface flow effects that can hinder accurate determination of the concrete load volume, the processor is configured to compare original batch volume and rheology of the concrete load monitored during drum rotation. The calibration of load volume involves a comparison between real-time data and historic data stored in processor-accessible memory, and further take into account the speed and tilt of the mixer drum (such as caused by roadway conditions), the concrete mix design, and other factors.
