ABSTRACT:
A modified reinforced non-porous cement composition and composite and the process of preparing same whereby the composites are reinforced using synthetic mineral fibers, such as glass and E-glass fibers. The cement includes a resin dispersion of a polymer, containing acid groups, with a mean particle size ranging from 0.05 and 5.0 microns and the resin dispersion protects the reinforcing fibers from alkaline attack. The water to cement ratio ranges from 0.2 to 0.5 and the weight ratio of the resin to the cement ranges from 0.02 to 0.4. Preferably, the resin dispersion is a thermoplastic resin prepared from monomers containing vinyl groups and the acid groups are preferably carboxyl groups.
