description: The study considers the problem of concreting massive structures and thick foundation slabs to analyze the behavior of early-age concrete, including temperature changes and associated thermal stresses. The dependence of temperature stresses for various thermal insulation options is investigated. Ambient air temperature of the concrete mixture influence on the stress-strain state of concrete blocks is studied. The stresses arising in the plate on the stiffness of the base are assessed. The modelling was carried out by the finite element analysis in the SIMULIA Abaqus software package. Goals that were achieved during the study: 1. Verification of the applied heat dissipation method. 2. Non-stationary thermal conductivity problem for various thermal insulation options and temperature conditions is considered. 3. Investigation of the effect of soil stiffness on the stress-strain state of a concrete slab. 4. Investigation of the stress-strain state of the plate under various thermal insulation options. 5. Assessment of the stress-strain state of concrete blocks during sequential concreting. The results of the work carried out are recommendations for choosing a concreting technique.
