Abstract

Corrosion of concrete sewer pipes as induced by sulphuric acid attack is a recognised problem which leads to premature collapse of pipes with further significant cost implications. To promote pro-active sewer management, easy and robust models require development based on reliable calibration data. This paper focuses on laboratory experiments of establishing concrete pipe corrosion rate by submerging test samples in a 0.8pH and a 1.5pH sulphuric acid aqueous solution for 120 days under 15ºC and 25ºC temperature regimes. The result deliver understanding of the interaction between the acidity, temperature and corrosion levels which can be further incorporated into a model.
