A lightweight gypsum compositions gypsum composition with good water resistance having a low water-to-stucco ratio, high flowability, and mechanical strength. The gypsum composition includes a cationic agent, an anionic agent, an aqueous stucco slurry containing a stucco, a water reducing dispersant, and water. The cationic agent may operate as a foaming agent, and the anionic agent may operate as a foam stabilizer.

Dispersion-based ready-to-use grout formulations, methods of making such dispersion-based ready-to-use grout formulations, and the resultant grout products that perform as reactive resin grout products. The grout formulations of the invention at least include a water-based acrylic polymer dispersion binder and optionally a water-based acrylate copolymer dispersion binder, in combination with one or more of an alkaline cross-linker, one or more silane adhesion promoters and/or a micro-fiber filler, along with various other constituents, to provide one-part ready-to-use grout formulations that require no mixing prior to use thereof. The resultant grout products of the invention meet performance standards of epoxy grout products, without requiring mixing of composition parts and without any adverse side effects.

A ceramic binder composition is disclosed as well as a method of making and using the same. Additionally, a ceramic coated separator used in, for example but without limitation, lithium ion batteries is disclosed.

The present invention is directed to a gypsum panel and a method of making such gypsum panel. For instance, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and a polyoxazoline. The methods of the present invention are directed to making the aforementioned gypsum panels by providing the first facing material, providing a gypsum slurry comprising gypsum, water, and a polyoxazoline onto the first facing material, and providing a second facing material on the gypsum slurry.

The present invention relates to the field of foam formation and stabilization, particularly foamed construction materials, such as cement. Disclosed are additives suitable to obtain mineral foams when added to the corresponding starting materials. The invention provides a ready-to-use product in the form of a solid particulate composition comprising hydrophobized particles (1) and catalytically active particles (2) as defined in claim 1. The invention further provides for manufacturing methods of such ready-to-use product.
