摘      要:The moisture transport in cracked cement-based materials was investigated with priority by numerical *** cracked cement-basis material was treated as two components system,including the cracks and cementitious *** mass balance between the water in the cracks and in the cement mortar was *** the modeling results,it was seen that the water or vapor filled the crack immediately when the cracked cementitious mortar was put into contact with the water or *** water/vapor penetrates into the mortar from the crack surfaces,as well as the external surface exposed in the outside *** existence of cracks increases the penetration of water/vapor into the cementitious *** the basis for studying the self-healing in cracked concrete,the simulation on moisture transport provided important information about the water distribution and movement inside the cracked concrete.
