Binding Isotherms

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.

Chlorido įsiskverbimo į betono struktūrą koeficientą galima būtų nustatyti išmatavus efektyviosios difuzijos koeficientą nustačius nelinijinį chlorido ir betono rišimąsi. Siūlomas naujas būdas rišimosi procesui modeliuoti—Freundlicho izoterma, apskaičiavus jos lygtį iš kelių tradicinių difuzijos bandymų pastoviosios būklės sąlygomis. Siūlomo būdo pranašumas (palyginti su klasikiniais bandymų metodais, kai rišimosi izotermos gaunamos iš trupintų bandinių) yra tas, kad taikoma nelinijinio rišimosi izotermos lygtis betono mikrostruktūrai natūraliomis eksploatacijos sąlygomis. Šiuo atveju galima studijuoti mikrostruktūros poveikį chlorido jonų rišimuisi.
