A process for preparing powdered dispersants comprising at least 90% by weight of at least one copolymer CP of the polycarboxylate ether type. The powdered dispersants can be easily dispersed in water. The invention also relates to the use of such powdered dispersants in mineral binder compositions, in particular dry mortars, concrete or gypsum formulations.

A regulating cementitious material for promoting hydration of Portland cement is provided. The regulating cementitious material may include ingredients by weight as follows: ye'elimite, 27˜68 parts; anhydrite, 29˜68 parts; lithium nitrite, 2˜5 parts; ethylene glycol monoisopropanolamine, 0.14˜0.29 parts; triethanolamine acetate, 0.04˜0.09 parts; and polyglycerol, 0.04˜0.09 parts. An early strength of Portland cement can be improved through a cooperative hydration between minerals and an enhanced solubilization of a complexing agent.

A method for the application of hydrous mineral binder compositions which contain fibres. An aqueous accelerator is mixed with the aqueous binder composition in a mixer shortly before the application. The method is very robust and makes it possible to quickly produce even large moulded bodies having a uniform surface and very good strength development properties.

The invention relates to a method for producing supersulfated cement, wherein pozzolanic and hydraulic aluminosilicate components and a calcium-sulfate-alkaline activation complex are mixed together. The calcium-sulfate-alkaline activation complex is produced by carrying out the following successive steps: a first step of mixing 70% by weight of calcium sulfate and 30% by weight of alkaline components; and subsequently; a second step of thermodynamically activating, by hot quenching, the calcium-sulfate-alkaline activation complex; and subsequently; a third step of cold quenching, by rapid mixing, the activated calcium-sulfate-alkaline activation complex with the pozzolanic aluminosilicate components.
