ACI 544.4R-18 PDF Download

ACI 544.4R-18 is a guide that provides engineers with design guidelines for using fiber-reinforced concrete (FRC) in structural and nonstructural applications. It acknowledges the advancements in materials technology and the valuable field experience to expand the applications of FRC. The guide emphasizes that fibers in FRC can be made from various materials and offer varying levels of tensile/flexural capacity for concrete sections, depending on factors such as type, dosage, and geometry.

The standard outlines the use of standard tests to evaluate the performance of FRC, including flexure, shear, and crack-width control, providing the necessary criteria for design purposes. It delves into specific applications of fiber reinforcement, such as slabs-on-ground, composite slabs-on-metal decks, pile-supported ground slabs, precast units, shotcrete, and hybrid reinforcement (combining reinforcing bars with fibers).
