Case Studies in Construction Materials, 2022 For longer spans of reinforced concrete elements, design codes dictate the use of sufficient lap splice length. Insufficient lap splice length decreases the flexural strength and ductility of reinforced concrete (RC) beams, while fiber addition improves ...

An Evaluation of the Acoustic Activity Emitted in Fiber-Reinforced Concrete Under Flexure at Low Temperature [PDF]
SensorsThis study investigated the changes in the acoustic emission (AE) activity emitted in fiber-reinforced concrete (FRC) under flexure at two temperatures (25 °C and −20 °C). Seven concrete mixtures were developed with different water-binder ratios (w/b) (0.

Performance evaluation of indented macro synthetic polypropylene fibers in high strength self-compacting concrete (SCC) [PDF]
Scientific ReportsAbstractConcrete is used worldwide as a construction material in many projects. It exhibits a brittle nature, and fibers' addition to it improves its mechanical properties. Polypropylene (PP) fibers stand out as widely employed fibers in concrete. However, conventional micro-PP fibers pose challenges due to their smooth texture, affecting bonding ...
