Title:
APPARATUSES AND SYSTEMS FOR AND METHODS OF GENERATING AND PLACING ZERO-SLUMP-PUMPABLE CONCRETE
Document Type and Number:
WIPO Patent Application WO/2018/130913
Kind Code:
A9
Abstract:
Methods, systems, and devices, are developed for creating a means of in-situ placement of a concrete mix that can have the thixotropy to hold vertical dimension without containment, while maintaining pliability to be pumped into place and manipulated to a desired shape, and can be combined with concrete set accelerators, allowing subsequent layers of this concrete mix to be continuously stacked in place to build tall walls and such without the use of forms. Concrete without these special properties is pumped toward the point of placement where it is modified by injecting and mixing, into that line of pumped concrete, an admixture containing thixotropes, thickeners and/or set accelerators or other modifiers to provide these properties and other improvements. A system is disclosed for defining a vertical or sloped concrete surface utilizing a movable beam attached to guide elements with sliding brackets, with the beam contact surface optionally having an active non-stick system.
