Polymer concrete is widely used in the field of construction due to its excellent mechanical properties and durability, but its long-term durability in high temperature and freeze-thaw environments still faces challenges.
The influence of commonly used thermosetting resins on the overall performance of polymer concrete has not been fully elucidated, and there is insufficient research on natural and expanded perlite as fillers, resulting in a lack of systematic guidance for actual engineering material selection.
