Implication

Experimental analysis reveals energy and structural changes in red sandstone subjected to acidic corrosion and dry-wet cycles, indicating significant deterioration effects.

Key Points

Peak strength and elastic modulus of red sandstone decrease significantly with more acidic dry-wet cycles, indicating deteriorating conditions.
Longitudinal wave velocity, total energy, and elastic strain energy show notable changes, with nonlinear increases seen with strain progression.
Analysis compared different damage models, showing the elastic modulus-based model better captures cumulative damage effects in red sandstone.
Findings underline the importance of understanding mechanical properties for evaluating geotechnical structures in acid rain-affected environments.
