Abstract

In the silicification of fibrous materials of vegetable origin, such as cotton waste, wood or cellulose fibres or straw, for the production of structural elements, the materials are opened up by the action of acid-forming bacteria until the materials are completely penetrated by acid, whereupon the growth of the bacteria is stopped and the fibrous materials are saturated with water-glass. The bacteria preferred are those which form lactic, acetic, citric or tartaric acid. In an example, chopped straw is added to a solution to which whey containing bacillus lactis aerogenes has been added and the mixture allowed to stand at 30-40 DEG C. for 4-6 hours, after which the bacteriological process is stopped by brief heating to 85-100 DEG C. or longer heating to 63-65 DEG C. and a 5 per cent water-glass solution is added. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification of the process in which the fibrous materials are saturated with an organic acid, particularly a fruit acid, and the bacteria are then added. This subject matter does not appear in the Specification as accepted.ALSO:In the silicification of fibrous materials of vegetable origin, such as cotton waste, wood or cellulose fibres or straw, for the production of structural elements, the materials are opened up by the action of acid-forming bacteria until the materials are completely penetrated by acid, whereupon the growth of the bacteria is stopped and the fibrous materials are saturated with waterglass.
