Abstract Production of Fibre-Reinforced Cementitious Composition A process for the production of a mouldable fibre- containing cementitious composition in which at least one mat of a water-insoluble fibrous material is contacted with at least one surface of a shaped article of a mouldable cementitious composition, the cementitious composition comprising a homogeneous mixture of at least one hydraulic cement, water in a proportion of not more than 25% by weight of the hydraulic cement in the composition, and at least one-water-soluble or water-dispersible polymeric material in a proportion of at least 1% by weight of the hydraulic cement in the composition. The mouldable cementitious composition may be in the form of a sheet and in the process two or more sheets may be used with a fibrous mat being sandwiched between adjacent pairs of sheets of cementitious composition. Also a mouldable fibre-containing cementitious composition and fibre-reinforced cement product produced by curing of the composition.
