Abstract

The method of mixing may affect the degree of agglomeration of particles in cement-based materials and thus the properties of the materials in their fresh, hardening, and hardened state. The larger the external force applied during mixing, the larger surface forces can be overcome and the smaller agglomerates will remain. The paper focuses on the effect of mixing schedule on self-compacting concrete properties. Workability and micro structure of a typical Danish self-compacting concrete mixed at varying intensity and with addition of superplasticizer in either one or two batches are described. The observations indicate that the most homogeneous concrete does not necessarily exhibit the lowest rheological properties.
