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.

Technical fields of building external wall decoration and material manufacturing, providing a mildewproof and antirot high-strength cement particle board and a preparation method thereof. The preparation method includes: (1) sequentially carbonizing and water-washing a shaving, and mixing the obtained carbonized shaving with a cement gelling agent, a curing agent aqueous solution and water to obtain a mixture; (2) molding the mixture to obtain a pre-molded material; and (3) sequentially curing and drying the pre-molded material to obtain the mildewproof and antirot high-strength cement particle board. Compared to ordinary cement particle board, which is not subjected to carbonization treatment and water-washing, the cement particle board of the present invention can effectively avoid mildew and rot, and can significantly improve the mechanical strength and durability thereof, helping to extend the service life of the cement particle board.

Method for producing a cementitious board (1), wherein a first liner (2) with first overlap sections (5) is provided and furnished with at least one layer of at least one slurry comprising a cementitious material (3); a second liner (4) with second overlap sections (8) is provided and arranged such that it contacts the first overlap sections (5) of the first liner (2), wherein the at least one layer of the at least one slurry (3) is arranged between the first liner (2) and the second liner (4); an adhesive foam (6) is provided at least partly on at least one of the first or second overlap sections (5, 8); and the first liner (2) and the second liner (4) are bonded via the adhesive foam (6) in the overlap sections (5, 8).

The invention comprises a cementitious material comprising a natural pozzolan selected from hyaloclastite, sideromelane or tachylite, wherein the natural pozzolan has a volume-based mean particle size of less than or equal to 40 μm. The cementitious material also comprising an aqueous alkaline activating solution suitable for forming a geopolymer. A method making a cementitious material is also disclosed.
