Abstract：Precast concrete segmental jointing technology uses epoxy adhesives to assemble the concrete joints,aiming to achieve"structural performance equivalent to cast-in-place"results.The performance of the epoxy adhesives is of great concern as it affects the safety and durability of these precast segmental jointed components.The national standard GB/T 44543-2024"Epoxy Adhesive for Precast Concrete Segmental Construction"has been implemented since April 1,2025.This article mainly interprets the background and significance,main content,technical highlights and innovation points of the standard,and compares and analyzes its main differences with the first domestic splicing adhesive product standard T/CECS 10080-2020"Epoxy Adhesive for Prefabricated Segment Assembly",to promote the effective implementation and promotion of the standard.
