Abstract
The specifications for concrete sand in Iowa have been used for many years with very good results. In several locations of the state, it is becoming more difficult to produce concrete sand consistently at a reasonable cost. Both ASTM and AASHTO have specifications for concrete sands that allow a finer, poorer graded sand than the Iowa specification. The ASTM and AASHTO specifications are based on the use of trial mix testing prior to construction. Iowa does not currently use the trial mix procedure.
