Review outlines assessment methodologies for fire-damaged concrete structures, indicating key implications for durability.
Concrete remains the most widely adaptable material utilised in construction field, known for its innumerable adaptability and strength. During its life span, concrete structures are subjected to several natural disasters such as earthquakes, landslides, cyclones and fire incidents. Fire events though are infrequent but in the event of their happening can have a notable impact. Despite a long-lasting and also not a combustible material, it does not offer complete resistance to fire events. This leads eventually to reduced durability & reliability. The paper presents study on damaged concrete exposed to fire conditions. It reviews several methodologies about assessing damaged concrete using non-destructive, semi-destructive and destructive examination. However, the evaluation of thermally damaged structures begins with visual inspection as a preliminary evaluation, followed by subsequent measurements and tests done on core samples. All these methods have their own advantages and limitation in assessing concrete subjected to fire. The present work compares the various testing methodologies based on their advantages and limitations.
