摘要： The present invention allows for better control over strength in concrete mixes and mix designs, while minimizing the over-use of cement and promoting sustainability within the industry. Disclosed are novel method and system which employ a diagnostic delta data (DDD) curve, or, in other words, data that displays a curvilinear relationship when plotted on a visual graph, as obtained by considering the differences (e.g., subtractive differences or ratios) as between (i) target slump and target (or maximum) water content, and (ii) slump and water content values as determined using an automated slump monitoring system which measures slump and water content in the concrete mix during delivery. This DDD curve can then be compared to monitored delta slump and delta water content for later or other deliveries, such that adjustments can be made to the concrete mix or mix design, in a manner that encourages avoidance of cement over-dosing or over-prescription.

摘要： 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.

摘要： Described are compositions and methods for controlled strength development in a hydratable cementitious material, and more particularly to the use of polymerizable monomer components, which are initiated and activated by a redox pair which are mixed in controlled fashion, for enhancing non-hydration strength within the matrix of the plastic hydratable cementitious material before setting of the cementitious material begins. Exemplary applications include minimizing pressures on formwork for high fluid ready-mix applications, enhancing support and bonding properties for integrated concrete slab work and other sequential applications, or facilitating speedy 3D printing applications, among other unique possibilities.

摘要： 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.

摘要： Described are a method and system for coordinating the delivery and placement of concrete loads at a job site, and more particularly to adjusting a set time value or value range of the concrete loads, thereby to facilitate finishing or other concrete placement activities. In exemplary embodiments, the adjustments can be made based on an assessment of previously placed concrete loads. The set time values or value ranges of the concrete can be monitored and adjusted to achieve desired properties during installation and/or in its hardened state.

摘要： 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.

摘要： The present invention relates to very high workable yet controllable concrete mix design, admixture composition, and process for placing concrete. The mix design relates to particular aggregate/cement ratios and types which are characteristic of ready mix concrete (RMC), which provide high fluidity reminiscent of self-consolidating concrete (SCC), and which provides advantages over both RMC and SCC in terms of ease and speed in placement and finishability at the construction site placement zone, regardless of whether into a horizontal formwork (e.g., for slabs, floors) or into vertical formwork (e.g., for blocks, walls, columns, etc.), without loss of control and without generating high risks of segregation even when small amounts of water are added at the size to facilitate finishing of the concrete surface. An inventive admixture combination which enables this unique design involves two different polycarboxylate comb polymers in combination with two specific viscosity modifying agents, and this combination provides highly workable concrete to be placed in a controlled, efficient manner.
