Numerical Prediction of Early-Age Cracking and Corrosion in High Performance Concrete Bridges - Case Study

This paper presents an evaluation of the effectiveness and the benefits of using high-performance concrete (HPC) containing corrosion inhibitors in the construction and repair of concrete bridges. Numerical models for predicting the early-age and in-service performance of HPC bridge structures are presented. The main parameters of these models, originally conceived for normal concrete, are revised and adapted for use with HPC containing corrosion inhibiting systems. The proposed models focus on the problems of early-age cracking, chloride ingress into concrete and corrosion of the conventional reinforcing steel. A case study of reinforced concrete (RC) barriers walls is used to illustrate the predictive capabilities of the models and the benefits of using HPC in extending the service life of bridge structures. Cost-effective mitigation measures for the prevention and control of cracking of HPC bridge structures are also suggested. For the covering abstract of this conference see ITRD number E211395.
