Аннотация
The use of special knowledge in the field of building materials science is increasingly in demand in modern legal proceedings when conducting judicial construction and technical examinations in order to obtain an evidence base, in particular, on determining the timing of construction work. It is known that when conducting expert studies, it is possible to assess the increase in concrete strength due to the continued hydration of cement and a decrease in the basicity (pH) of the surface layer of concrete due to the processes of carbonization of cement stone in interaction with the atmosphere. The paper presents proven mathematical dependencies that make it possible to link the temporary change in the strength of concrete and the carbonation of the surface layer of concrete laid in monolithic structures with the structural parameters of concrete and its durability. These dependencies give the construction expert a fundamental opportunity to determine the age of concrete by changing the specified characteristics of concrete and, consequently, to determine the time period in which the construction structure was created from this concrete. Thus, expert determination of the production time of monolithic concrete structures is possible and is based on conducting research to establish the actual strength of concrete and determine the depth of its surface carbonation at the time of expert research. The described methodology for determining the timing of construction work on the manufacture of monolithic concrete structures in building conditions was used when conducting forensic examination.
