A sound-absorbing and fire-insulating wall covering includes, a cured mixture of: (i) 5-20% by weight mineralized wood fibre; (ii) 20-60%/by weight sand with an SiO2 content of less than 5% by weight and a greywacke content of at least 30% by weight; and (iii) 20-50% by weight cement. A method of preparing a fire-insulating wall covering includes a step of mixing, relative to the cured weight, 5-20% by weight mineralized wood fibre, 30-60% by weight sand with an SiO2 content smaller than 5% by weight and a greywacke content of at least 30% by weight, and 20-50% by weight cement. Then 10-30% by weight water is added. Thereafter the mixture is cured to form the fire-insulating wall covering.

A wall covering as claimed in claim 18, wherein the sand contains at least 50% by weight greywacke. 20. A wall covering as claimed in claim 1, containing about 25 to about 40% by weight cement. 21. A wall covering as claimed in claim 1, containing: i) about 10 to about 15% by weight mineralized wood fibre; ii) about 35 to about 50% by weight sand with an SiO2 content less than about 2% by weight and a greywacke content greater than about 50% by weight; and iii) about 25 to about 40% by weight cement. 22. A wall covering as claimed in claim 1, containing about 0.1 to about 1% by weight impregnating agent. 23. A wall covering as claimed in claim 22, containing 0.1-0.5% by weight impregnating agent. 24. A wall covering as claimed in claim 1, containing about 30 to about 500 grams per m2 impregnating agent. 25. A wall covering as claimed in claim 24, containing 100-250 grams per m2 impregnating agent. 26. A method of preparing a fire-insulating wall covering comprising a cured mixture of: i) about 5 to about 20% by weight mineralized wood fibre; ii) about 20 to about 60% by weight sand with an SiO2 content of less than about 5% by weight and a greywacke content of at least about 30% by weight; and iii) about 20 to about 50% by weight cement; wherein relative to a cured weight of the mixture are mixed about 5 to about 20% by weight mineralized wood fibre, about 20 to about 60% by weight sand with an SiO2 content less than about 5% by weight and a greywacke content of at least about 30% by weight, and about 20 to about 50% by weight cement, and about 10 to about 30% by weight water is then added, where after the mixture is cured to form the fire-insulating wall covering.
