Abstract
ABSTRACT In this article, the role of chloride transport parameters in the service life estimation of a reinforced concrete structure is discussed. This article also lists several qualitative and quantitative test methods used to measure resistance to ingress of chloride in concrete systems with their advantageous and critique properties. The relationship between the rapid assessment methods such as resistivity and the diffusion coefficient is put forward. A review of the ageing coefficient for different binder types is presented. The importance to characterise and account for the environmental factors such as exposure condition and ambient temperature variation is emphasised based on its impact on the chloride build-up rate. A parametric study is carried out to identify the role of different factors associated with chloride transport property in service life estimation. The prediction of chloride build-up rates for various binder composites based on analytical and numerical approaches is summarised along with relevant input parameters.
