A new approach for modelling the ingress of deleterious materials in cracked strain hardening cement-based composites

Abstract

Strain-hardening cement-based composites (SHCC) are characterised by their tensile ductility and high strain capacity. Due to their intrinsically small crack widths, SHCC exhibit favourable transport conditions in the cracked state compared to conventional concrete for certain transport mechanisms, e.g. diffusion and permeation and thus a good durability potential In this paper the Ingress Potential Index model is proposed which is a novel way of expressing the potential ingress of deleterious materials into cracked SHCC with a single value taking into account the strain level, crack pattern and a chosen ingress process. For the demonstration of the model, experimental data of water transport and chloride penetration into cracked concrete was used in combination with observed SHCC crack patterns. The purpose of this paper is to present an approach which can be used for any crack-linked ingress process and different distributions of crack widths. Future work is required to verify this novel approach experimentally.
