Simulation of Coupled Corrosive Product Formation, Migration into Crack and Propagation in Reinforced Concrete Sections
Source abstract
Abstract
This paper aims to numerically simulate corrosion induced cracking, its propagation over sections of reinforced concrete members and the penetration of corrosive gel product into crack gaps. A coupled steel core and surrounding corrosion product are mechanically represented by a fictitious growing composite, with which the corrosive cracking initiation and subsequent propagation are simulated by 2D nonlinear crack analysis. The injection of corrosive gels into evolving cracks is substantiated in cases where corrosive cracks stably propagate such as large covers and/or comparatively small diameters of steel, and the coupled system of gel formation, migration and crack propagation is newly presented. The simulation scheme was verified through RC sections subjected to accelerated corrosion by electric current with regard to crack patterns and critical corrosion rates when cracks reach the outer surface of members.
