A holistic model for cement paste and concrete chloride diffusion coefficient

Abstract

Strength and durability are pivotal for designing sustainable concrete structures. For reinforced concrete, chloride diffusion coefficient is a measure for durability. Phenomenological multi-scale models are proposed for quantifying chloride effective diffusion coefficient of bulk cement paste (DCl bcp) and concrete (DCl c). DCl bcp model accounts for w/cm, and cement composition and degree of hydration. DCl c model comprises of DCl bcp, …
