Study on Anchoring Characteristics and Freeze–Thaw Degradation Law of the Cement-Based Early-Strength Anchor in Freeze–Thaw Regions

This article focuses on the effect of freeze–thaw cycling a cement-based early-strength anchor material, compressive strength which at 24 h is 14 times that ordinary cement, and 7 twice cement. The setting time required to achieve expected 1/7 Through indoor tests, appearance changes, quality loss, microstructure changes in after 0, 5, 15, 25, 50, 75, 100 cycles were studied, revealing evolution mechanical properties micromechanisms material under conditions. sample failure criteria determined, evaluation indicators reflecting degree damage defined, their relationships with number fitted assess durability environments. provides theoretical reference for further improvements adaption different
