Described are cementitious reagent materials produced from globally abundant inorganic feedstocks. Also described are methods for the manufacture of such cementitious reagent materials and forming the reagent materials as microspheroidal glassy particles. Also described are apparatuses, systems and methods for the thermochemical production of glassy cementitious reagents with spheroidal morphology. The apparatuses, systems and methods makes use of an in-flight melting/quenching technology such that solid particles are flown in suspension, melted in suspension, and then quenched in suspension. The cementitious reagents can be used in concrete to substantially reduce the CO.sub.2 emission associated with cement production.

A magnetizable concrete wireless power transfer pad can include a base, an inductive coil and a pillar. The base can comprise a magnetizable base concrete including concrete and first magnetizable particles, the first magnetizable particles having a magnetic permeability and a magnetic saturation. The inductive coil can be positioned directly adjacent and centered over the base, the inductive coil forming an inductive coil gap at its center inner perimeter between a conductive wire that form the inductive coil, the inductive coil having an outer perimeter, a lateral width, and a longitudinal length. The pillar can extend up from the base through the inductive coil gap, the pillar comprising a magnetizable pillar concrete including concrete and second magnetizable particles, the second magnetizable particles having a magnetic permeability and a magnetic saturation such that the base and the pillar collectively shape an external magnetic field produced by the inductive coil to increase the mutual coupling with a receiver pad, that way increasing the power transfer capabilities of the system.

The present invention is a manufactured, geometric shaped aggregate intended to replace the gravel or rock aggregate used in a concrete mixture. The geometric shaped aggregate is provided to be solid or hollow. In an embodiment, the hollow aggregate is filled with insulating material or an adhesive solution to fill cracks formed from stress. Electronic components and sensors may be disposed in the hollow aggregate to gather metrics from the solution. In another embodiment, permeable aggregate can allow for moisture mitigation within the concrete structure. The preferred geometric shape of the aggregate is a tetrapod, but other geometric shapes which are known to naturally interweave or intertwine may be used.

A particulate sound absorption board and its preparation method. The said particulate sound absorption board consists of binding agent and sound absorption particle; the external surface of sound absorption particle is covered with a layer of binding agent, and the angularity coefficient of particle covered with binding agent is less than 1.3; the said sound absorption particle consists of skeleton particle and filling particle, in which the former is used for sound absorption board skeleton, and the latter flows into the pore between skeleton particles to form sound absorption pore, and the average diameter of cross section of sound absorption pore is 0.07 mm. The two-stage manufacturing technology (i.e. coating, curing and then shaping) is adopted for the said preparation method to prevent the pore between particles from being blocked by excess binding agent, and further improve the angularity coefficient of particle.
