Benefits to plastic concrete: Improved workability – The small, spherical shape of fly ash particles provides a "ball bearing" effect that creates a concrete paste with superior plasticity. Decreased water demand – Replacing cement with fly ash reduces the water demand for a given slump and, in certain situations, can even reduce drying shrinkage.

The GEOMAX soil stabilization process blends Class C self-cementing fly ash (a coal combustion by-product), kiln dust, quicklime or cement powder into the soil to bond soil particles. Fly ash can be used as a drying agent for saturated soils because it helps reduce the moisture content and allows for compaction – resulting in a more stable base.

In the wet process and long dry process, all of the pyroprocessing activity occurs in the rotary kiln. Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter.
