<p>A method of mass treating organic fibrous material, e.g. wood fibres or waste pulp, comprising (i) contacting the organic fibrous material with a mixture of an organic polymer precursor and sodium silicate (water glass) and (ii) contacting the treated fibrous material with an acid, preferably sulphuric acid, to deposit an organic precursor/silica hybrid or an organic precursor/silicic acid hybrid or an organic precursor/polysilicic acid hybrid on the treated fibrous material and then (iii) contacting the treated fibrous material with an aluminium compound. The produced hybrid construction material (hybrid fibre composite precursor) has improved surface water permeability, improved fire resistance, improved early flexural strength and it can be used as a reinforcing material, e.g. in cement or concrete.</p> |
