What Makes Concrete Pumpable?| Concrete Construction Magazine

For best pumpability, coarse aggregate grading should fall in the center of the gradation specifications. Porosity will affect pumpability if a significant amount of mix water is absorbed by the aggregate during pumping. When absorption causes problems, one solution is to thoroughly wet the aggregate stockpiles before batching the concrete.
