AbstractAbout AuthorsReferences
Criteria of the efficiency of high-strength and ordinary concretes with reference to the main characteristics of the used binder (activity and Portland cement consumption, normal concentration of cement paste etc.) with due regard for the impact of main factors (water-cement ratio, rheotechnological indicators and workability of concrete mix, concrete density, economic costs) on the main mechanical characteristic, compressive strength, have been developed. Boundary values of proposed indicators characterizing the transfer to advanced technologies of the concrete science (high-strength composites, self-compacting concrete mixes etc.) have been established. Testing of indicators, when analyzing compositions of fine concretes with natural and anthropogenic fillers, has been performed. The efficiency of introducing a large quantity of fine-disperse marble flour in the binder composition and modification of compositions with active mineral additives is shown on the basis of the developed criteria.
