ABSTRACT

Abstract Study of theoretical basis of negative temperature effect onto structure formation and solidification processes of various concrete's based on various binders allows to formulate a working hypothesis that reads the following. High water-resistant plaster binder hydration rate accompanied with chemical binding of large amount of mixing water and with significant exothermic effect and with accelerated formation of primary plaster stone crystal structure, pre-determines quick strength growth rate of the binders and concrete's made on the basis of binders at negative temperatures and thus provides high structure early-age freeze strength, Provided reduction of concrete mixture water consumption and provided formation of fine-porous structure one may enable low primary moisture and solidification of concrete at negative temperatures.
