ACI 544.2R-17 PDF Download

ACI 544.2R-17 is a comprehensive report that discusses the measurement of fresh state properties and fiber dispersion in fiber-reinforced concrete (FRC). The report provides detailed information on the testing procedures for both ordinary vibrated FRC and fiber-reinforced self-consolidating concrete (FR-SCC). It reviews various test methods that can be used to assess the fresh state performance of FRC, including slump flow, J-ring, and V-funnel tests, among others.

Furthermore, the report focuses on the measurement and evaluation of fiber dispersion in FRC materials and structures. It presents methods for nondestructive monitoring of fiber dispersion and orientation, providing insights into the effectiveness and limitations of these techniques. The report also addresses the advantages and disadvantages of different approaches to analyze fiber dispersion in FRC.

By highlighting the importance of measuring fresh state properties and fiber dispersion in FRC, this ACI standard serves as a valuable resource for researchers, engineers, and technicians involved in the design and production of fiber-reinforced concrete. It offers guidance on the appropriate testing methods and provides recommendations for improving fiber dispersion in FRC to enhance its mechanical properties and performance.
