Физико-Химические Основы и Технологическая Эффективность Беспрогревного Производства Дисперсно-Армированных Композитов

Abstract

The article examines aspects of the energy intensity of precast concrete production and the negative influence of steam curing on the formation of concrete structure. Based on the thermodynamic approach and the theory of heterogeneous nucleation, the possibility of transitioning to non-steam curing technology is considered. A mathematical model of strength development kinetics based on the Arrhenius equation is presented, and the role of carbonate microfillers in reducing the activation energy of the hydration reaction is demonstrated. Special attention is paid to the specifics of fiber reinforced concrete hardening: it is proven that the elimination of steam curing minimizes thermal deformations of polymer fibers, preserving the integrity of the adhesive bond.
