THE  ROLE  OF  SPIN  EFFECTS  IN  STRUCTURE  FORMATION  OF  CEMENT  MIXTURES

The paper presents a new approach to the cement hardening mechanism allowing for efficient interactions. Changes in paramagnetic centre concentration in the course of hardening of type M400 Portland cement and type M600 high-strength cement are described in this paper. It is shown that changes observed in the paramagnetic centre concentration are associated with recombination processes of paramagnetic centres and amorphization of the basic polycrystalline structure. From the spin chemistry viewpoint, four possible kinds of water molecular configurations.

Keywords: cement; spin chemistry; electron spin resonance spectroscopy; hardening; strength; paramagnetic centre; recombination.
