• Abstract:
  The concrete used on highway projects is mostly Portland cement concrete, a mixture of ; Portland cement, a coarse granular material called aggregate, and fine granular material, often ; sand. While chiefly a filler, aggregate’s properties strongly affect the properties of concrete made ; with it. Most aggregate produced in Florida, called limerock, is a type of local limestone which ; tends to be more porous, softer, and less ; dense than limestone from other U.S. regions. ; It is generally assumed that this difference ; produces a less strong concrete, so, additional ; Portland cement is used to compensate, ; leading to increased cost for concrete ; including limerock.
