Abstract:
Dispersion-based ready-to-use grout formulations, methods of making such dispersion-based ready-to-use grout formulations, and the resultant grout products that perform as reactive resin grout products. The grout formulations of the invention at least include a water-based acrylic polymer dispersion binder and optionally a water-based acrylate copolymer dispersion binder, in combination with one or more of an alkaline cross-linker, one or more silane adhesion promoters and/or a micro-fiber filler, along with various other constituents, to provide one-part ready-to-use grout formulations that require no mixing prior to use thereof. The resultant grout products of the invention meet performance standards of epoxy grout products, without requiring mixing of composition parts and without any adverse side effects.

Abstract:
A method of placing a flowable construction material including a hydraulic binder for building structural components layer-by-layer, such as for 3D concrete printing, the method including preparing a fresh flowable construction material made of Portland cement, fine limestone filler materials, fine sands, water, and water reducing admixture and possibly a set or hardening accelerating admixture, conveying the flowable construction material to a deposition head, placing the construction material through an outlet of the deposition head in order to form a layer of construction material, before placing the construction material, adding a rheology-modifying agent to the construction material so that the placed material has an increased yield stress when compared to the material during the conveying step.
Abstract:
A salt-tolerant, thermally-stable rheology modifier and, in particular, a rheology modifier for applications in oilfield well-bore fluids. In accordance with one aspect, the rheology modifier comprises a terpolymer of acrylamide, 2-acrylamido-2-methyl-propanesulfonic acid (AMPS) and a long-chain alkyl acrylate wherein the terpolymer is prepared by dispersion polymerization.

Abstract:
A wellbore strengthening composition may include a base fluid and at least one polymer functionalized with electrochemically activated groups. A method of treating a wellbore may include emplacing, in at least a selected region of the wellbore, a wellbore strengthening composition including a base fluid and at least one polymer functionalized with electrochemically activated groups. The method may also include emplacing a downhole tool capable of generating a voltage potential in the wellbore and applying a voltage potential in the wellbore with the downhole tool.
Abstract:
The present description relates to asphalt coating compositions, and methods of application, for coating asphalt paving surfaces. In particular, sprayable coating compositions are provided, and methods of application, for coating asphalt paving surfaces. In the coating composition, a lightweight aggregate material of sprayable particle size is stably suspended in a sprayable asphalt emulsion in an amount sufficient to increase the micro-texture surface roughness of the cured coating.
