The present disclosure provides an aqueous composition comprising a quaternary amine compound neutralized with a polycarboxylic acid. The aqueous composition is particularly useful for inerting clay in cement compositions as well as compatibilzing pigments in pigment dispersions.

The present invention relates to a construction material composition comprising at least one non-ionic copolymer and the use of said construction material composition. Further, the present invention relates to a non-ionic copolymer and the use thereof for modifying robustness against clay deviations.

An accelerator for mineral binder compositions, especially for mortars or concrete, including: aluminium sulfate, at least one pozzolane, optionally at least one defoamer, and water. The accelerator is particularly useful for shotcrete, in the field of free-forming construction, or for additive manufacturing.

The circumference coating material fills a recessed groove that is formed on a circumferential surface of a honeycomb fired body and extends an axial direction at which a part of cells are opened to the outside and to cover the circumferential surface, thereby forming a circumferential wall on the circumferential surface of a honeycomb structure, and the circumference coating material includes colloidal silica in a part of raw materials to be used and has a chlorine concentration of 150 ppm or less. In addition, the colloidal silica to be used has a chlorine concentration of 500 ppm or less, and the colloidal silica is produced using at least any one acid of sulfuric acid, phosphoric acid, and organic acid.

The present disclosure provides an aqueous composition comprising a quaternary amine compound neutralized with a polycarboxylic acid. The aqueous composition is particularly useful for inerting clay in cement compositions as well as compatibilzing pigments in pigment dispersions.

The invention relates to a retarding mixture comprising sodium gluconate and alkali hydrogen carbonate, an alkali-activated binding agent containing sodium gluconate and alkali hydrogen carbonate and a method for adjusting the strength development, wherein sodium gluconate and alkali hydrogen carbonate are added to an alkali-activated binding agent.
