The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

A method for processing incinerator bottom ash (IBA) comprises the steps of carbonating IBA aggregate material by CO.sub.2 sequestration and providing a stabilizing additive for mixing with the carbonated IBA aggregate material, wherein the additive comprises one or more components from group (b1) and one or more components from group (b2), wherein group (b1) consists of aluminium chloride and at least one other metal chloride, and wherein group (b2) consists of silica, zeolite and apatite. When the carbonated IBA and additive is mixed a stabilized IBA composition is formed, the stabilized IBA composition being suitable for use as a substitute for traditional aggregates in the manufacture of concrete and concrete products.

This invention provides a co-disposal pollution control method of municipal solid waste and fly ash leached by membrane concentrate, obtained residue and application thereof. A co-disposal pollution control method of municipal solid waste and fly ash leached by membrane concentrate, comprising the following steps: heat treating the mixture of leached ash and municipal solid waste at 800-1100° C. to obtain residue; the leaching ash is fly ash after being leached with membrane concentrate. The invention solves the problems existed in the co-disposal treatment of membrane concentrate, incineration fly ash and municipal solid waste, and the leaching toxicity of the ash leached by the membrane concentrated solution is reduced, moreover, the leaching concentration of heavy metals in the residue obtained after the leaching treatment is treated with municipal solid waste at medium and high temperature, and the residue obtained after heat treatment can be used as building materials.

Methods, compositions, and apparatuses are provided herein that utilize polystyrene from recycled products to make a high strength composite concrete that can be used for subgrade utility vaults, utility trenches, etc. Polystyrene is a widely-used plastic that can be collected and then densified at particular parameters including temperature to transform the polystyrene to a usable form. Then, the densified polystyrene is combined with other resin materials and dry materials to form a high-strength concrete material. The amount of densified polystyrene that is combined with the other materials is critical to control shrinkage and expansion of the concrete material during manufacturing.

A mixer and a mixing unit for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The mixer (6) comprises: a bucket part (27) for loading and transferring the side-stream material; a mixer apparatus (26) for mixing the side-stream material which has been loaded into the space delimited by the bucket part (27); a connecting device (25) for connecting the mixer (6) to a boom of a work machine (5); and at least one measuring device (S1, S2, S3) for determining properties of the material in the mixer (6).

An arrangement and a method for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.
