Abstract

Abstract

En 中文
• Multiscale phase-field model for coupled sulfate attack and calcium leaching. • Unified porosity evolution couples transport, reaction, and damage. • Two-step homogenization links pore-precipitation to mortar degradation. • Porosity-dependent degradation captures leaching-induced matrix softening. • Buffer-to-precipitate ratio explains the wavy expansion behavior.
