<p>The present invention provides a method of producing articles containing cement and reinforcing vegetable fibres. Hitherto, the fibres had to be treated chemically in order to ensure sufficient bonding between the cement and the fibres. The present invention removes the need for the chemical pre-treatment of the fibres and involves a two stage process of mixing the cement powder, water and the fibres. In the first stage, the cement and water are mixed together to give a homogeneous mixture which is then admixed with the fibres. The resulting slurry is then formed to shape and allowed to set.</p> |
