An insulation material formed of a composition, and a method of making an insulation material is provided. The composition forming the insulation material includes magnesium oxide; at least one of magnesium chloride, magnesium sulfate, and hydrates thereof; water; a foaming agent; a thickener; and a foam stabilizer. The composition is foamed to promote aeration of the composition to reduce density of the insulation material formed from the composition.

Provided herein are compositions and methods of carbonation processing for the fabrication of cementitious materials and concrete products. Embodiments include manufacturing processes of a low-carbon concrete product comprising: forming a cementitious slurry including portlandite; shaping the cementitious slurry into a structural component; and exposing the structural component to a CO.sub.2 waste stream, thereby enabling manufacture of the low-carbon concrete product.

Curable resin compositions comprising an epoxy resin and a hydrazide curing agent and methods for using the curable resin compositions in cementing and/or remedial operations in a subterranean formation are provided. In one embodiment, the method may comprise combining an epoxy resin and a curing agent to form a curable resin composition, wherein the curing agent comprises a hydrazide curing agent; introducing the curable resin composition into a subterranean formation; and allowing the curable resin composition to at least partially cure.

The method is for use with a substrate having a plurality of parallel channels extending therethrough. In the method, the steps comprise: filling a selected plurality of the channels with a granular material; and consolidating the granular material through heat. The selected plurality of channels is selected to produce a wall that separates the substrate into: a first portion having a first plurality of the parallel channels extending therethrough; and a second portion having a second plurality of the parallel channels extending therethrough.

The invention comprises a concrete form. The concrete form comprises a first panel having a first primary surface for contacting plastic concrete and a second primary surface opposite the first surface, wherein the first panel is made from a rigid plastic sheet or a metal sheet; and a second panel spaced from the second primary surface of the first panel, wherein the second panel is made from a rigid plastic sheet or a metal sheet. The concrete form also comprises a layer of insulating material disposed between the first panel and the second panel. A method of using the concrete form is also disclosed.
