Abstract
The design concept was developed for a new kind of fly ash-rich fine concretes characterized by a very good workability and high stability against segregation, while at the same time being free from the well-documented problems associated with the conventional sandrich and sand concretes. The new design concept leads, with the help of fewer mortar tests, to an easily workable concrete with high stability against segregation by using regional typical basic materials. The mortar tests are relatively easy and quick, and for practical considerations they are very efficient in mix-designs. There are fairly comparable characteristics in strength development, durability and deformation comparisons between ordinary hardened concretes and concretes with 8 mm and 2 mm maximum grain size. Thereby the fine concrete with low cement content has significantly favourable fresh concrete behaviours. A concrete witch was composed by the design concept was successful tested in a precast.
