摘要

The concrete with a higher ultimate strength than can be achieved according to the water:cement ratio law consists of a blend of intimately mixed aggregates, cement and water. The quantity of water used is determined by the requirements of processability. The aggregates are determined with respect to their grain size by the grading curve, and a predetermined proportion consists of extremely fine-grained material. As a result of this extremely fine-grain material, which can especially be fly ash, the aggregate structure is so close-packed that, in the set concrete, at least a substantial part of external forces is transmitted via the concrete aggregate.
