    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: 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.

    摘要: The present invention provides a composition and method for modifying a hydratable cementitious composition such as concrete or mortar using at least three different, distinct carboxylate polymers, even when clay is present in the concrete or mortar that would otherwise diminish dosage efficiency of polycarboxylate polymer used as dispersant. The three polycarboxylate polymers, designated as Polymer I, Polymer II, and Polymer II, are derived from monomer Components A, B, and C wherein Component A is an unsaturated carboxylic acid, Component B is a polyoxyalkylene, and Component C is an unsaturated carboxylate ester. The component molar ratio ranges for A:B:C are different as between Polymers I and II; while a distinct component molar ratio A:B+C is identified for Polymer III. When treated with these three different polycarboxylate polymers, the hydratable cementitious composition is surprisingly enhanced in terms of initial workability and slump retention, especially if clay is present.

    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 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.

    摘要: Described are admixture composition and method for integrally waterproofing cementitious compositions, such as concrete and mortar, wherein an organosilicon compound (e.g., silane) is mixed with animal oil, vegetable oil, or mixture thereof, and defoaming agent. The organosilicon/oil mixtures of the present invention enhances the water repellent efficacy of the organosilicon, even as it displays inherently greater product stability, as compared to emulsion-based (and thus substantial free-water containing) admixture formulations of the prior art. Cementitious materials made in accordance with the present invention demonstrate excellent air consistency and air neutrality.
