Based on a comprehensive experimental study on carbon fiber reinforced cement composites incorporating the Ashland's industrial grade carbon fiber reinforced cement composites incorporating the Ashland's inductrial grade carbon fibers (Carboflex), the optimum mix variables and processing techniques were decided. The types and proportions of different mix constituents, the fiber lengths and volume fractions, and the mixing and curing procedures which produce desirable fresh mix properties and superior hardened material performance were decided. A comprehensive experimental data set on the performance characteristics of carbon fiber reinforced cement was also generated. The research was performed in three phases: (1) Establishment of the mixing procedure and mix proportions for achieving desirable fresh mix characteristics; (2) Assessment of the trends in the effects of different mix variables on the strength of air cured specimens and further optimization of the mix proportions for achieving superior strength characteristics in addition to the desirable fresh mix workability; and (3) Optimization of the curing condition and full mechanical characterization for carbon fiber reinforced cement composites with some optimum values of fiber length and volume fraction. A comprehensive investigation was performed on the material properties and structural applications of steel fiber reinforced concrete. In studies on the application of steel fiber reinforced concrete a load bearing structural elements, the effects of steel fibers on improving the strength and ductility of concrete footings under bearing pressure, and enhancing bond between deformed bars and concrete were investigated.
