High-Strength Concrete Composition Design: Current Trends

Abstract

A rational proportioning of the main components of high-strength concrete—cement, aggregates, water, and additives—has been determined, ensuring minimal cement consumption while maintaining optimal technical and technological performance characteristics required for concrete mix design. The concrete composition has been selected using an analytical-experimental method, optimizing the preparation of mixtures within permissible limits. The following factors must be considered: concrete strength at compression (class), ease of placement, compaction coefficient (Кg > 0.98), cement activity, actual and overall porosity, granulometric composition of sand and gravel, as well as the type and quantity of modifiers.
