Title of the articleThe directed technology of concrete and reinforced concrete
Abstract.Problem statement. The aim of the work was theoretical and experimental study of stage-surface mechanism of cement hydration. Results. The scheme of stage («hopping» after V.A. Kindu) hardening of clinker binders (Portland cement and its varieties) with the role electrical surface processes that is the basic principle of the kinetics of heterogeneous reactions. Conclusions. Hydration conversions include staging formation at the interface of «clinker grain – water» phase of transitional metastable energy composition with its development (accumulation of private power), reaching a critical level and decay (the appearance of the active elements and the chemistry of the phenomenon); textural – phasic contraction under the influence of the developing vacuum system cement grains, sealing and hardening of the contact surface areas by means of «sprawling» amorphous C-S-H. Specification of the morphology of the hardened cement paste (microconcrete) feature of which is the presence on the surface of the hydrated cement particles dispersed locally residual surfactants areas requiring indispensable accounting in concrete science theory and practice of construction. Given a number of technological methods, providing increase of physical and technical properties, structural stability and operational reliability of concrete and reinforced concrete.
Keywords.concrete, reinforced concrete, hydration, staging process, microconcrete, surface-active area, discharges of strength, reliability and concrete.
