IMPACT OF CHLORIDES ON REINFORCED CONCRETE: SIMULATION OF ITS INGRESS IN CONCRETE
Abstract
The paper presents a model for evaluation of environmental conditions that influence on reinforced highway structures. The models is applied for calculation of chloride ingress in concrete structures while using de-icing salt.
