The article presents a comprehensive study on the weathering of building stones under a Csa Mediterranean climate simulation. The research focuses on predicting decay in construction materials, which is essential for assessing their long-term performance. It emphasises the significant impact of greenhouse gases, particularly CO2, on the decay processes of building stones. Efflorescences were observed on the stones after 6 months of accelerated ageing, predominantly located above water films in the rising dump fronts. The presence of halite (NaCl) on sandstone subjected to seawater capillary rising highlights the effects of water on stone decay.
The study involved various testing methods, including ultrasonic velocity and Leeb D hardness tests. The Velocity Reduction Index (VRI) was calculated based on the velocity measurements, and a portable hardness tester Leeb D EQUOTIP was used for hardness measurements. These tests provided valuable data on the response of building stones to weathering and capillary rising waters.
The research findings offer insights into the complex interaction between building materials and environmental factors, aiding in the prediction of material behaviour over time. By referencing additional studies, the article provides a comprehensive overview of the research conducted in this field, encouraging further exploration of related topics.
Overall, the study contributes significantly to understanding the decay mechanisms of building stones and their response to weathering processes, ultimately enhancing the knowledge base for sustainable construction practices in challenging climatic conditions.
