9986 METHOD OF INCORPORATING CARBON FIBERS INTO CEMENT TO PRODUCE REINFORCED STRUCTURES HAVING IMPROVED FLEXURAL STRENGTHS Method of incorporating carbon fibers into an aqueous hardenable hydraulic cementitious matrix to produce a formable composition which can be set to produce a reinforced structure having improved flexural strength, and improved resistance to cracking and spalling, which employs a polyethylene oxide in an amount sufficient to effect separation of the individual fibers of the fiber strands present in the mix and uniformly disperse them throughout the mix.
