A system and method, according to one or more exemplary embodiments, for a fireproof, soundproof, lightweight cement and wood composite wall system that is very inexpensive, outlasts wood frame homes, and replaces many building materials in one installation whereby the composite wall system may be formed from wood shavings, cement, calcium chloride, and water mixed at high speed for air entrainment.

The present invention provides an apparatus for manufacturing artificial marble, which includes a granite soil storage unit configured to supply a granite soil by storing, drying, and heating it, a granite soil heating unit configured to heat the granite soil supplied from the granite soil storage unit, a resin storage unit configured to store a thermoplastic polyurethane (TPU) resin maintained in a solid phase at room temperature, a mixing-transporting unit configured to accommodate the TPU resin and the heated granite soil therein and then melting and mixing them to produce and simultaneously transport an artificial marble slurry, a material guide unit configured to guide the granite soil and the TPU resin into the mixing-transporting unit, a discharge unit configured to discharge the artificial marble slurry mixed in the mixing-transporting unit by a certain amount, a mold supply unit configured to continuously supply a mold for accommodating and molding the artificial marble slurry therein, a mold guide unit configured to guide the mold supplied from the mold supply unit downward of the discharge unit to accommodate the artificial marble slurry in the mold, a forming unit configured to form an artificial marble by applying vibration and pressure to the artificial marble slurry accommodated in the mold, an extraction unit configured to extract the mold accommodating the artificial marble, and a lamination unit configured to laminate and store the mold extracted by the extraction unit.

Provided herein are compositions, methods, and systems comprising vaterite and magnesium oxide.

The present invention relates to the use of a soluble magnesium compound for adjusting, in particular reducing, the viscosity of an aluminum sulfate suspension.

The present invention relates to the use of a soluble magnesium compound for adjusting, in particular reducing, the viscosity of an aluminum sulfate suspension.

The present invention relates in part to an alkali-silica reaction mitigation admixture comprising an organic or inorganic salt that provides an aluminum, calcium, magnesium, or iron cation. The present invention also relates to a method of mitigating the alkali-silica reaction in a concrete product. The invention is further related to kits comprising the alkali-silica mitigation admixture and an instruction booklet.

Provided is a cover for asphalt including an asphalt emulsion and a method of paving asphalt using the same, and specifically, to a cover for asphalt, which may facilitate adhesion between an existing asphalt pavement layer and a new asphalt pavement layer and substitute for a tack coat. The cover for asphalt prevents an asphalt emulsion from being damaged by heavy vehicles or construction equipment moving for application of a new pavement layer, and allows omitting separate asphalt emulsion application and curing processes before application of the new asphalt layer.

Provided is an asphalt reinforcement, and more particularly, to an asphalt reinforcement, which is applicable to asphalt pavement without tack coat application and curing processes, and a method of repairing asphalt pavement using the same. The asphalt reinforcement of the present invention includes: a reinforcing fiber layer having a plurality of holes formed therein; a film layer, which is breathable or non-breathable, includes at least one resin selected from the group consisting of polypropylene, polyethylene, ethylene vinyl acetate, polyethylene elastomers, polypropylene elastomers, polybutene, and thermoplastic polyurethane, and has a melting point of 90° C. to 130° C.; and a nonwoven fabric layer, which is disposed between the reinforcing fiber layer and the film layer, is impregnated with an asphalt emulsion, and has a melting point of 50° C. to 130° C.

Provided herein are compositions, methods, and systems comprising vaterite and magnesium oxide.

Methods, compositions, and tools for use in creating rapidly forming plugs in situ in subterranean formations. In one instance, the disclosure provides a method that includes: placing a first pill comprising a calcium-aluminate-based cement composition at a plug location within the wellbore with the tubing; and placing a second pill comprising an alkaline fluid composition into the wellbore adjacent to the first pill with the tubing. In some cases there is a spacer fluid or spacer device between the first pill and the second pill. In some cases tubing having a mixing device is located at the bottom of the tubing in the wellbore to aid I mixing the first pill and the second pill to facilitate a chemical in situ reaction of the first pill and the second pill. The reaction between the first pill and the second pill forms a set plug at the plug location.
