The present invention relates to a method for producing a gypsum-containing foamed prefabricated building material and to a gypsum-containing foamed prefabricated building material.

Methods and compositions comprising an emulsion or a microemulsion for use treating an oil and/or gas well are provided. In some embodiments, the emulsion or the microemulsion comprises an aqueous phase, a solvent, a surfactant comprising alkyl polyglycoside, an alcohol, and, optionally, one or more additives.

Electromagnetically-induced cement concrete crack self-healing diisocyanate microcapsules include raw materials, in parts by weight, comprising 15-55 parts of petroleum resin, 5-10 parts of paraffin, 5-10 parts of polyethylene wax, 3-10 parts of magnetic iron powder and 20-67 parts of diisocyanate. The diisocyanate microcapsules use the diisocyanate as a core material, and the petroleum resin/paraffin/polyethylene wax/magnetic iron powder mixture as the shell of the capsule. When micro cracks occur in the concrete, the crack propagation can break partial of the microcapsule inside, the diisocyanate inside the microcapsules flows out and diffuses into the crack and is subjected to a solidifying reaction with water in the concrete, so that the crack is repaired in time; and for the microcapsules that are not broken by cracks, external electromagnetic field can be applied to melt the shell to release the diisocyanate inside, thereby diffusing into cracks and solidify with water to repair them.

A strain tolerant recycled bitumen pavement composition comprising aggregate, recycled bitumen, and a specialized polymer modified bitumen. The specialized polymer modified bitumen may comprise bitumen and polymer, where the polymer comprises a preponderance of butadiene. The amount of recycled bitumen in the composition may be greater than 5% of the composition. Such high levels of recycled bitumen in a pavement composition, while desirable both economically and environmentally, typically produces layers with poor strain tolerance. The strain tolerance of the layer produced with the composition of the present invention, however, may be significantly higher due to the inclusion of the specialized polymer modified bitumen.
