A fiber reinforced cementitious product comprises a cement as a continuous phase and fibres dispersed as reinforcement in the continuous phase, the product including a polyelectrolyte and a finely divided inorganic material having a high surface area present in (a) admixture with the cement, (b) as a size coating on the fibers or (c) both. The fibers are preferably glass but may also be other natural and synthetic inorganic and organic fibres. The inorganic material may be pentonite, fumed silica or diatomaceous earth. The cementitious product may be made by Hatschek, Magniani, or filter press processes. |
