Abstract
This study investigates the autogenous self-healing mechanisms in carbonated natural hydraulic lime mortar exposed to cyclic compressive loads. We sought to explain the observed 40% surge in residual compressive strength compared to the quasi-static compressive strength following fatigue testing at frequencies of 5 Hz, 0.5 Hz, and 0.05 Hz [Theoretical and Applied Fracture Mechanics 118 (2022) 103201]. Central to our investigation is the hypothesis that cyclic loads mobilize the embedded water in the mortar, catalyzing chemical reactions that foster autogenous self healing. To substantiate this, intact and post-compressive fatigue specimens were analyzed using differential thermal analysis (DTA), thermogravimetric assessments (TGA), mercury intrusion porosimetry (MIP), and scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX). The TGA-DTA highlighted the evolution of new hydration pathways, characterized by C-S-H gel and portlandite formation. The MIP results indicated a decline in pore volume, particularly in fine pores, affirming the synthesis of novel hydration compounds. The SEM-EDX analysis further authenticated the composition of these emergent microstructures. This work, therefore, presents a comprehensive understanding of the factors influencing autogenous self healing in lime mortar systems.
