Described are admixture composition and method for integrally waterproofing cementitious compositions, such as concrete and mortar, wherein an organosilicon compound (e.g., silane) is mixed with animal oil, vegetable oil, or mixture thereof, and defoaming agent. The organosilicon/oil mixtures of the present invention enhances the water repellent efficacy of the organosilicon, even as it displays inherently greater product stability, as compared to emulsion-based (and thus substantial free-water containing) admixture formulations of the prior art. Cementitious materials made in accordance with the present invention demonstrate excellent air consistency and air neutrality.

The present invention refers to a new concrete composition comprising fiberglass waste and an air-entraining additive. The concrete presents a thermo-insulating performance far superior to conventionally produced concretes. The present invention is mainly intended for the construction industry, in non-structural applications for thermal insulation. The use of fiberglass waste reduces the consumption of natural aggregates and allows for the use of waste which is expense to dispose of.

In general, the present invention is directed to the use of particular phosphorus containing compounds for making a gypsum board. The phosphorus containing compound may be a phosphite or a phosphate having a certain formula. In this regard, the present invention is directed to a slurry for making a gypsum board wherein the slurry includes such phosphorus containing compound. The present invention is also directed to a method of making a gypsum board from the slurry as well as a resulting gypsum board.

The disclosure discloses an ultra-dry three-phase flue gas foam for oil-gas fields and preparation method thereof. The ultra-dry three-phase flue gas foam is produced by a gas phase, a liquid phase and a solid phase; the gas phase is a flue gas; the foaming solution is an aqueous solution of a surfactant, a pH adjuster, and an inorganic salt; the solid phase is a composite of fly ash and nano silica; the foam quality is 90%-99%. The solid phase foam stabilizer is a compounded system of fly ash particles and nano silica particles, which is not only low in cost but also can form a stable solid particle adsorption layer on the foam film. Thus the instability of the foam such as film rupture, gas diffusion and bubble aggregation can be greatly reduced, and the stability of the foam can be effectively improved.

A composition including: a lignin sulfonic acid-based compound and a water-soluble compound; a lignin derivative that is a reaction product of the lignin sulfonic acid-based compound with an aromatic water-soluble compound; or the lignin sulfonic acid-based compound, the water-soluble compound, and the lignin derivative. The composition is a granular product or a liquid product.
