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. This method allows conventional plant batching with commonly available constituent materials for batching an economical concrete that is delivered to a jobsite and then is pumped most of the way to a point of placement, before inline modification; allowing minimal conveyance and pumping of a zero-slump and set-accelerated concrete mix, avoiding difficulties and risk associated with pumping such a modified concrete mix. Various means of metering the injection of the admixture flow rate to correspond proportionally to the concrete flow rate are also disclosed. Alternatively a means for modifying a volumetric concrete batching and mixing system to achieve the same result is disclosed. 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.

Mixing elements for static mixer utilizing mixing low- to high-viscosity components are provided and comprise a planar central part extending along a longitudinal axis L and having front and rear faces, wherein arranged on the front and/or rear face are at least two flow-influencing elements that each surround at least one through-opening located in the central part and that are each in the form of prism lateral surfaces that are substantially perpendicular to the front and/or rear face, wherein pairs of the elements overlap or are connected to one another at a lateral edge. Static mixers comprising the mixing element and methods for mixing low- to high-viscosity components with the static mixers are also provided.

The system is provided for generating a mixed methane gas feed stream using at least one source of biogas and an alternate source of methane gas. The system includes a biogas subsystem, a control device for the methane gas from the at least one alternate source of methane gas, and a vertically-extending gas mixing vessel.
