Evaluating Steel Corrosion and Concrete Deterioration for Improved and Sustainable Urban Development in Acid Sulfate Soils (COMPASS)

Introduction

Acid sulfate soils (ASS), common in the Finnish coastal areas and globally, challenge civil construction stability. Soil acidification through chemical and microbial processes can compromise the durability of reinforced concrete structures, yet the degradation mechanisms and the role of microbes remain poorly understood. COMPASS aims to evaluate steel corrosion and concrete deterioration associated with the chemical and microbial conditions in ASS, and to develop modelling tools that predict the lifespan of concrete structures. A more comprehensive understanding of how ASS affect reinforced concrete will be developed, and effective mitigation strategies will be identified. This multidisciplinary approach will address end-user needs by providing assessment tools for civil engineering structures. The research consortium, consisting of early-career researchers from VTT and GTK, will adopt diverse expert perspectives and contribute innovative knowledge to sustainable urban development in ASS environments.
