Abstract
A process for the production of a moldable 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 moldable 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 moldable 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 moldable fibre-containing cementitious composition and fibre-reinforced cement product produced by curing of the composition.
