ACI SP-343:2020 PDF Download

The ACI SP-343:2020 standard is a document that addresses the use of fiber reinforced concrete (FRC) in engineering practice. The standard is a result of international workshops and conferences held by organizations such as RILEM and ACI. These events aimed to identify applications, guidelines, and research needs for FRC in order to facilitate its transfer to professional practice.

The standard covers various aspects of FRC, including mechanical characterization, shear behavior, and its use in bridges, elevated slabs, precast elements, and tunnel linings. It also addresses the performance of FRC under seismic and special loading conditions, as well as its durability and serviceability. The goal of the standard is to provide the state-of-the-art knowledge in terms of specifications development and actual applications of FRC, and to promote collaborative efforts among researchers, designers, industry representatives, and government officials.

The standard includes a table of contents that lists the topics covered in the document, such as round-robin tests for flexural behavior, optimization of quality control procedures, the influence of fibers on shrinkage and cracking mechanisms, shear behavior of FRC, and the structural behavior of precast tunnel segments with macro-synthetic fibers, among others. It also acknowledges the support from sponsoring organizations, industry stakeholders, and participants from around the world who contribute to the advancement and acceptance of FRC in structural applications.
