Compositions and systems for bidirectional energy transfer and thermally enhanced solar absorbers
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.
EMULSION COMPOSITIONS FOR PRIMING A PAVEMENT SURFACE
Aqueous base- or acid-stabilized emulsions are provided for use on a pavement surface, and for use in an aqueous priming base emulsion that is used for priming a pavement surface. Any of the emulsions can be applied to a pavement surface to form a primed pavement surface, and then cured so that the pavement is available for use in preparing a pavement.
High-strength flowable fill compositions
High-strength flowable fill compositions are disclosed. The compositions include cement, aggregate (e.g. sand), water, coloring agent, polymer, and fibers. In an embodiment, the compositions include an accelerant, e.g., calcium chloride and/or an air entraining agent. The compositions have a compressive strength of between 10 psi and 500 psi after 1 day, a compressive strength of between 300 psi and 1300 psi after 7 days, and a compressive strength of between 1000 psi and 2500 psi after 28 days.
Polymer Concrete with Plastic Aggregate and Fines
A composition that may include a resin, plastic aggregate, plastic fines, and optionally fly ash. The plastic aggregates and plastic fines may be formed from recycled plastic. The composition may be utilized to repair damaged surfaces, including damages concrete surfaces. The composition may further be used in pre-formed structures. The pre-formed structures may include panels that are assembled to form an upright enclosure, such as a shelter.
CRACK SEALANT METHOD AND COMPOSITION FOR REDUCED COLOR CONTRAST
