Success on the first attempt was not expected by “experts”.
• Reviewing leading textbooks, like “Reinforced Concrete: Mechanics…” by James Wight, and thirty years of engineering reports informs you that one cannot significantly increase the tensile strength of concrete by adding fibers. In fact, interesting tests for Fiber Reinforced Concrete (FRC) like ASTM 1609 are not as commonly performed today because of this general understanding.
• The TNSR Delivery Mechanism continuously streams Ultra High Molecular Weight Polyethylene (UHMWPE) fibers, today’s strongest production fiber. FRC applications to this point have always used chopped fibers (~2″) added into the concrete mixer.
