Method and system to measure and monitor the grey water content in a rotating concrete mixer drum mixer truck using a sensor attached to the interior of the concrete mixer drum. By measuring the grey water content before a batching process takes place, the batched water (and cement content and admixture type and content) can be modified in order to maintain expected performance of the batched load in terms of both strength and rheology, or more simply, some or all of the grey water can be discharged from the concrete mixer drum before batching.

A composition and method for stabilizing or consolidating low permeability soil, rock, coal, mineral, or other loose aggregates, especially in a subterranean environment. Disclosed is a two-component, acrylate-based injection resin that includes a first component and a second component. The first component comprises an acrylate and an accelerator, and the second component comprises a radical initiator. At the application site, the components are mixed together to form a liquid resin mixture with sufficiently low viscosity, such that the mixture can permeate the low permeability soil. The mixture is injected into the soil in need of stabilization and undergoes polymerization and curing, in turn forming a subterranean geocomposite having high compressive strength.
Disclosed are methods, compositions, and composition packages for spray-coating a membrane for waterproofing a concrete tunnel applications. After primer coating is applied onto a surface in the tunnel, the coating composition is sprayed to form a membrane, and then concrete is cast or sprayed against the membrane so that it can bond to the membrane. Coating compositions comprise two or more acrylate monomers, as well as initiator, accelerator, and optional additive. Preferably, the coating composition is established by using a two-part package, one part having initiator, the other part having accelerator, and each part containing the monomers and optional additives so that the two parts can be shipped to the application site and mixed in a 1:1 ratio during spraying. The waterproofing coating composition provides excellent bonding with concrete.
A method for manufacturing a concrete article is disclosed. The method comprises coating a mould or formwork with a release agent; spraying a mortar onto the mould or formwork, thereby forming a layer of mortar; casting concrete into the mould or formwork and onto the layer of mortar; and allowing the concrete to hydrate and harden in the mould or formwork, whereby a concrete article having a mortar skin layer is provided. The invention also provides concrete articles made by the described methods, and concrete structures which comprise the concrete articles. Concrete articles having the mortar skins can be made to have a relatively uniform outward appearance, even if the concrete cast behind the mortar skins may be different, in composition or appearance. Pigments or colorants and other expensive admixtures can be used in the mortar skin composition to greater visual effect, since the use of the mortar skin is less in overall volume compared to the concrete articles as a whole.
An integrated air barrier assembly is provided as an integral product in which a fastener-sealing layer is secured between opposed surfaces of a board and an anti-blocking facing layer. The assembly exhibits good fastener sealability, including for larger self-drilling screws. The anti-blocking facing layer maintains the fastener-sealing layer inward of the environment and prevents blocking or sticking of the assembly when stacked. In some embodiments, the anti-blocking facing layer can be a metal film or foil, which can reflect heat away from the fastener-sealing layer, thereby maintaining a lower temperature on the fastener-sealing layer. In some embodiments, the board can be an insulating layer or wood layer. The assembly can be readily installed in a single step during construction.

The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.

A composition and method for stabilizing or consolidating soil, rock, coal, mineral, or other loose aggregates, especially in a subterranean environment. A hydroswelling admixture of polyurethane prepolymers and hydrophobic plasticizer is injected or pumped into the interstices of loose aggregates. The admixture is a single component system and has a low viscosity. The admixture reacts with water that is naturally present in the subterranean environment or with water that is simultaneously pumped in prior to or concurrent with the admixture. Upon reaction, the product polymerizes and swells to a polyurethane foam, in order to stabilize the loose aggregates.

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.

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.

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.
