Alternative aggregate sources or additional aggregate blending can then be considered to approach the elusive "ideal" gradation that provides the best workability, pumpability, reduced shrinkage, and economy (Figure 1). Note that eliminating the sand from a mix transforms conventional concrete to a "no-fines" mix, also known as "pervious" concrete" (see Pervious Concrete Pavements). Pervious ...
