Extruded fiber reinforced cement matrix composites and method of making same

摘要

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 is made by mixing cement, water, water soluble binder, and relatively short, discontinuous reinforcing fibers, preferably short polyvinyl alcohol fibers, to provide an extrudable mixture, the extruding the mixture to shape, and curing the cement.
