摘要： A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

摘要： Systems and methods of shotcrete construction are contemplated whereby guide rails are placed in proximity and forward to a shotcrete receiving surface, with any guide rails disposed directly in front of the shotcrete receiving surface being configured to be offset from the receiving surface allowing shotcrete to be sprayed behind the offset guide rails. Following application of shotcrete, a screed configured to engage with and traverse along at least two of the guide rails may be used to rod the shotcrete via a protruding region of the screed extending beyond the guide rails, thereby removing excess shotcrete and imparting to the shotcrete surface a contour at least partially defined by the configuration of the guide rails and the configuration of the protruding region of the screed. Complex, precise, and even exotic architectural shotcrete installations may be created in this fashion by providing a suitable set of guide rails and screed.

摘要： Methods, systems, and devices, are developed for 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.

摘要： A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).
