This paper outlines a project (namely PAT-ASR) which entails the development of a multi scale material performance assessment model on simulation of alkali silica reaction deployment and its effects on concrete durability. Performance models require a multi scale approach from micro (namely reaction chemistry) to macro level studies (namely structural mechanics). PAT-ASR aims to combine the tasks of guidelines on ASR prevention and control in a comprehensive integrated tool. This project involves experimental studies, among others including the determination of mechanical properties of ASR gel. A computational model, in conjunction with the already developed Lattice Models, will be used for simulating crack patterns in a concrete matrix. A statistical approach to sample data, harvesting from literature, can be used to increase the reliability of such a prediction model. Final integrated support tool will provide a guideline for engineers on ASR conscious design and a full-scale technical report on the subject.
