要旨 Frost damage of mortar and concrete is an important issue for structures in some cold and wet areas. This paper presents a precise simulation work considering non-uniformly distributed moisture and heat field. Coupled heat and moisture governing equations with ice formation are applied into a discrete numerical method (RBSM). Water penetration profile and thermal lag matches the experiment evidence well. Finally, deformation and cracking at different locations of the mortar specimen due to freeze and thaw cycle (FTC) are simulated, which happens non-uniformly in target specimens.
