<p>This fibre reinforced cementitious composite having improved post-cracking strength comprise an inorganic cementitious matrix having embedded therein a mixture of chopped fibres, one of the fibres being brittle, highly stiff fibre selected from glass, asbestos and mineral fibres, and another of the fibres comprising a tough, flexible fibre selected from polypropylene, polyethylene, polyamide, polyimide and polyester. The use of such fibre mixtures enables stronger composites to be produced, containing larger total quantities of fibres without experiencing the processing difficulties of requiring very large amounts of water for their preparation.</p> |
