Abstract:
In the present research project, fly ash was mechanically processed to 1 to 5 micron particle size. Mortars and concretes were made from these processed fly ashes. In this paper, the results of the micronized fly ash are compared to the results gained with air classified fly ash, silica fume, and blends. It was found that using ground fly ashes, very fluid mixtures can be produced with excellent strength and durability properties. Because of the growing interest in ultra-fine supplementary cementing materials (SCM's) for high-performance concrete, there is a need to find ways to micronize fly ashes in an economical way.
