AbstractAbout AuthorsReferences
The article describes the results of experimental studies of self-compacting fine concretes on the basis of composite binders prepared with the use of mineral micro-fillers. The aim of this work was to study the kinetics of structure formation and the impact of the introduction of mineral micro-fillers of various hydration activity on the characteristics of fine concrete, for obtaining self-compacting fine concrete with improved crack-resistance and durability. As raw materials were used: plain base Portland cement with different fine disperse mineral micro-fillers in the form of carbonate flour, fine-grinded quartz sand after its mechanical-chemical activation, an expanding additive on the sulphate-aluminate basis. Has been conducted the study of the kinetics of structure formation and physical-mechanical properties of fine concrete on the basis of composite binders with mineral micro-fillers at different stages of structure formation.
