The Impact of Aging Patterns of Cyclic Freezing-Thawing on Brinell Hardness of Penoplex
At present, when studying the influence of climatic factors on the characteristics of various materials, preference is given to accelerated (laboratory) methods of aging. These methods, in contrast to natural methods, allow obtaining results in a short period of time with little effort. However, the question arises about the adequacy of the adopted aging patterns, i.e., how effective are the adopted patterns with a real change in the characteristics of the material. In this paper, using the example of studying the Brinell hardness variation in Penoplexas a function of the accepted aging schemes (simulation by alternate freezing and thawing), the importance of this problem is shown. Aging patterns are characterized by a certain amount of time spent by the sample in the soaking state and in the freezer.
