lufeng Yang

Abstract


Transport mechanism and influential factors of chloride ion in two different stages to atmospheric transport and concrete Transport were explored and an improvedmulti-factor model for surface chloride concentration in concrete structure Exposed to Marine atmosphere Zone was developed . firstly , The main influential factors onsurface chloride Concentration were investigated , and , influential laws of various Factors, including Marine environmental Conditions, concrete material Properties Then exposure time , and on surface Chloride concentration were explored . taking into consideration this Influences of, various important factors such as distance from theSea,wind speed , Water -to-binder ratio, Binder types and exposure time , Improved multi-factor model for surface chloride concentration of concrete structure Exposed To          marine atmosphere Zone was developed based on Marine Field data of multiple Locations including European,north American, South American and Asian data and Two-level multiple Nonlinear regression analysis . Finally , The accuracy and applicability of the Proposed model were demonstrated by comparing with
