Chloride Binding of Self-compacting Concrete with Different Crack Depths under Electric Migration Test

摘要：

Cracks can form a shortcut for transport of chloride ions in concrete structure, and provide more opportunities for chloride ions to contact and bind with cement matrix. Following the NT BUILD 492 chloride migration test method, chloride content were determined on cracked concrete samples which were prepared by artificial crack method. The results shows crack depth increased from 0 mm to 31.4 mm almost did not exert pronounced effects on chloride binding of concrete under the migration test. Besides, the binding parameter of linear binding isotherms almost did not change.
