| dc.description.abstract | This thesis evaluates the use of fibrous reinforced concrete as a viable structural repair alternative. An independent laboratory investigation was conducted to substantiate the validity of the marketed claims of Polypropylene Fiber Reinforced Concrete (PFRC) and of Steel Fiber Reinforced Concrete (SFRC) to improve the long-term performance of conventional portland cement concrete. The study found that SFRC significantly increases the compression strength, flexural behavior, and material toughness of PCC, whereas the test response for PFRC yielded minimal contributory strengths. The work examines the function of fibers; FRC's historical background, prevalent economic considerations, and modern repair applicational developments; remedies to overcome the negative aspects of SFRC; current research programs; and future trends. The author recommends trial field demonstration of Steel Fiber Reinforced Micro-Silica Dense Concrete (SFR-MSDC) as a cost-competitive material alternate in lieu of non-fibrous Latex-Modified Concrete (LMC) to more proficiently rehabilitate fatigue-distressed bridge decks. | |
