Modern activation methods for binder and concrete mixtures (review)

The article presents a review and analysis of the activation methods for binders and concrete mixtures. It compares various grinding aggregates allowing various degrees of thinness through pressing. The study concludes that, though the solid-phase activation method is effective, yet the liquid-phase activation is cheaper. In the rotary pulsation apparatus, under heavy mechanical action on the aqueous solution of polymer, there takes place a destruction of polymolecules with the emergence of a great number of active groups which can contribute to the polymerisation of organic molecules, that is the emergence of polymer structures that are more complex than the original ones. Among the non-reactive methods of activation of building mixtures and their components, one of the promising ones is the treatment with high-voltage electric discharges.
