Abstract
This article is the second in a series devoted to summarizing and analyzing numerous published materials on the thermomechanical properties of concrete exposed to high temperatures. This article provides an overview of experimental data related to the study of concrete properties under shortterm heating and attempts to analyze and structure the results of numerous, diverse tests related to the study of concrete properties under short-term high-temperature heating. The physics of concrete deformation during heating and its causes are discussed. The dependence of the obtained characteristics on test conditions is demonstrated. The key factors influencing the strength and deformation properties of concrete during heating are highlighted. Concepts regarding the mechanisms of thermal degradation and thermal resistance of concrete are developed, supported by specialized methods for studying concrete and its components. The main causes of changes in the strength and deformation properties of concrete during short-term high-temperature heating are presented, with an emphasis on identifying the influencing factors and their degree of influence, as well as summarizing existing interpretations of degradation mechanisms.
