Resource-saving technologies for advanced concrete in the Republic of Bashkortostan

摘要

Properties of both organo-mineral superplasticized unmodified and modified concretes are considered, impact of workability of concrete and water-binder ratio on strength properties of concrete are analyzed herein. Gonsistent aggregate grading with minimum void, accordingly with maximum packed density under optimum content of dispersed particles in concrete is to be applied to make mortars and concrete with stable properties and less variations in values. The proposed solution enables to simplify proportioning as different combination of aggregates is not required for each proportion. Comparative analysis of various fillers being by-products and materials for making mortars and asphalt-concrete has been made. The results for reinforced steel consumption reducing together with efficient combination of higher grade concrete were considered at amending the “reinforced-concrete structures” section. Computational algorithms made under economic and mathematical methods to improve construction solutions over the reinforced concrete frame are given. Efficient engineering solutions to use high strength concrete and rebar that were applied in some facilities are proposed.
