Aging of Structural Materials Modified with Polymer Additives in Cold Climate Conditions

Abstract:

Currently, one of the main materials for the construction of buildings and structures is concrete. Improving the performance of concrete is a priority of modern scientific research. Low climatic temperatures, frequent transitions through zero degrees in the autumn-spring seasons, and other aggressive factors have a significant impact on the mechanical and operational properties of structural materials. This work presents the experience of modifying heavy concrete M200 with polymer additive Amokor KM. In the process of two summer field tests, there were obtained data on the persistence of the strength characteristics of the material at test temperatures of-60 and + 20, fractographic studies of the initial and aged samples were carried out, as a result, it was found that the modification positively affects the durability of concrete M200. Additional protective staining increases the durability of the tested materials. Keywords: concrete, strength, composite, compression, modification, durability, fractographic studies.
