Study of the Behavior of Cement Composites in the Conditions of Cyclic Exposure Positive and Negative Temperatures

Abstract

Abstract The paper presents the results of tests of cement composites under the conditions of cyclic exposure to negative and positive temperatures for 45 days. The stability factor (durability) compares the compositions with various fillers and additives. Resistance (long-term preservation of the structure and properties) of composites was estimated from the change in the relative hardness of the material, characterized by the area of the polygon, obtained as a result of a piecewise linear approximation of the exposure points of the test materials.
