<p>This invention relates to fibre reinforced cement composites and method for forming the same. The method includes the steps of mixing together dry solids and not more than 30% water by mass, based on the total dry solids contents of the mixture. The dry solids include at least one hydraulic cement, chemical pulp lignocellulosic fibre, and at least one selected silicecous substance. The mixture is formed and pressed to a predetermined density and/or dimension, with conditions of humidity thereafter being maintained for a period of time to advance setting reactions in the mixture. A fibre reinforced product is thus produced. The selected silicecous substance is defined as a natural, waste or manufactured material containing at least 50% silica and having a bulk density in descrete particle form of not more than 1200 kg per cubic metre, selected from a defined group.</p> |
