摘要：Improved structural members including solid and hollow core beams, poles,columns and enclosure structures formed of a cement-based slurry infiltrated fibercomposite material. The improved structural members are produced by first placing aplurality of individual short fibers or fiber mats of organic or inorganic materials into aform to create a bed of fibers substantially filling the form and having a predeterminedfiber volume density and then adding a cement-based slurry mixture into the form tocompletely infiltrate the spaces between the fibers. Existing structural members may beretrofitted with jackets of the cement-based slurry infiltrated fiber composite material.The cement- based slurry mixture includes a composition of Portland cement or blendedcement, fly ash, water, a high-range water reducer (superplasticizer), and may also includefine grain sand, ground granulated blast-furnace slag, chemical admixtures, and otheradditives. Due to its fiber volume density and method of manufacture, the resultingstructure has greater strength, less maintenance, and less cracking and deteriorationthan wood, steel, or conventional reinforced concrete and pre-stressed concretestructures, and a much higher bending capacity approximating that of structural steel.
