DURABILITY ASSESSMENT OF CELLULAR CONCRETE THROUGH STRENGTH EVALUATION UNDER ADVERSE ENVIRONMENTAL CONDITIONS

Abstract

This article presents the results of durability assessment for various types of cellular concrete. The research was conducted on aerated concrete samples utilizing a two-stage foam introduction method, classical foam concrete method, and autoclaved aerated concrete. Adverse factors affecting the material's durability were attributed to the influence of natural-climatic conditions, including temperature cyclicality (both low and high), cyclic wetting (immersion), wind cyclicality, and aggressive environments. The tests were conducted under the following combined exposures: cyclic freezing with prior immersion, cyclic exposure to high temperatures with and without immersion, and exposure to a 10% sulfuric acid solution. Durability loss patterns were observed for each type of adverse exposure based on the experiment duration. An evaluation of the resistance of specific materials to particular adverse influences is provided based on the obtained results. The findings underscore the importance of material selection based on specific operational conditions and contribute to the development of more durable construction materials for use in aggressive environments.
