Abstract
An extruded fiber reinforced cement matrix composite having substantially improved tensile strength with strain hardening behavior and substantially improved tensile strain, and improved flexural properties in three-point bending. The composite is made by mixing cement, water, water soluble binder, and relatively short, discontinuous reinforcing fibers, preferably short poly vinyl alcohol fibers, to provide an extrudable mixture; then extruding the mixture to shape, and curing the cement.
