Abstract

Abstract

En 中文
• CGFA dosage governed sulfate and freeze-thaw durability of AACGFAM. • 20% CGFA delivered the best overall durability performance. • Moderate CGFA refined pore structure and lowered cumulative pore volume. • Excessive CGFA increased crack connectivity and transport pathways. • Dual deterioration mechanisms were clarified by XRD, SEM, FTIR and BET.
