Influence of mixing procedure on mechanical properties of high-performance concrete

Popis výsledku v původním jazyce

Mechanical parameters of cementitious composites are primarily determined by the composition of cement matrix. In case of high performance concrete (HPC), high-quality compounds and increased amounts of cement are exploited to obtain the best possible properties of the material. As these components are expensive, the aim is to use them with maximum efficiency. With optimized procedure of homogenization of compounds, parameters of concrete can be improved without changing the composition of the mix. Several mixing procedures were applied to a selected HPC mix. Compressive and flexural strength of particular batches were compared. The results showed that the compressive strength of HPC made of the same compounds can vary by almost 30 % just due to amendments of the mixing procedure, while the flexural tensile strength was almost indifferent to the homogenization technique used.
