Mathematical Modeling of Technologically Controlled Processes Determining the Durability of Concrete and Reinforced Concrete Structures

The paper presents modern approaches to mathematical modeling of processes determining the durability of concrete and reinforced concrete structures, with a focus on the role of construction technology parameters. Durability is considered as a result of coupled physico-chemical and physico-mechanical processes formed during mixing, placing, and curing of concrete. The fundamental mechanisms of mass and heat transfer, chemical reactions, and damage evolution governing the changes in concrete structure and properties over time are analyzed. Durability modeling methods are systematized, including deterministic analytical models, numerical methods, coupled multiphysical models, and probabilistic approaches. Special attention is paid to the methodological gap between construction technology and structural analysis. The necessity of integrating technological parameters into predictive models as key factors influencing material performance is substantiated. Proper formulation of boundary conditions reflecting real curing and service conditions is shown to be essential for reliable service life prediction. Mathematical modeling is considered as a tool for durability management throughout the life cycle of a structure — from mix design to operation and monitoring.
