ACI SP-345:2021 PDF Download

ACI SP-345:2021 is a standard that focuses on textile-reinforced concrete/fabric-reinforced cementitious matrix (TRC/FRCM) materials. The standard highlights the results and findings from technical sessions organized by ACI Committee 549 in collaboration with RILEM TC MCC. These sessions aimed to collect information and present knowledge on TRC and FRCM as sustainable construction materials.

TRC is used for new construction applications, while FRCM is used for repair applications of existing concrete and masonry structures. Both methods utilize a textile mesh as reinforcement and a cementitious-based matrix component. These composite systems possess high tensile and flexural strength, as well as ductility, making them suitable for supporting structural loads.

The standard discusses the various types of textiles that can be used for reinforcement, including polymer-based, glass, natural, basalt, carbon, steel, and hybrid textiles. It also considers different types of matrices, such as cementitious, geopolymers, and lightweight matrices with aggregates. Additionally, the standard covers the use of additives like short fibers, fillers, and nanomaterials.

The technical sessions were attended by researchers, designers, students, and professionals from the construction and fiber industries, facilitating the sharing of knowledge and collaboration. The standard includes a table of contents listing the different topics covered in the sessions, such as carbon reinforced concrete under cyclic tensile loading, shear capacity of TRC slabs, performance of TRM/TRC systems under elevated temperatures and fire conditions, and many others.
