Over two billion tons of natural aggregate are produced each year in the United States and that number is expected to increase to 2.5 billion tons by 2020.

The use of fiber reinforcement in Portland Cement Concrete (PCC) has recently become a popular option in concrete construction because of its influence on preventing segregation, reducing early shrinkage cracks and increasing residual load capacity.
