Prediction and prevention of concrete deterioration: New approaches based on multi-criteria analysis (AHP)

Concrete, despite its inherent robustness, is susceptible to various forms of degradation that can threaten the lifespan of infrastructures. This article investigates new approaches for predicting and preventing these degradations, with a focus on the Analytic Hierarchy Process (AHP). It begins by examining the critical mechanisms of concrete degradation, including chemical attacks such as sulfate dissolution and alkali-aggregate reactions, as well as aggravating factors like seawater exposure. The AHP is presented as a powerful tool for assessing degradation risks by accounting for the multitude of factors involved. The article demonstrates how AHP can be employed to prioritize risk factors based on their relative importance, quantify the influence of each factor on the durability of concrete, and develop targeted and optimized prevention strategies tailored to the specific conditions of each project. The aim is to provide engineers and construction professionals with a robust decision-making framework based on rigorous scientific methodology to enhance the durability and resilience of concrete structures.
