Tampa FL, May 10th 2013 – Preferred Materials beat out 6 other entrants to win the 3rd annual strength competition put on by the Suncoast Chapter of the American Concrete Institute. The rules were simple: an entry consisted of a set of 3 – 4×8 cylinders. No cylinder could have a compressive strength below 3000 PSI or above 5000 PSI. The set of cylinders with the lowest strength variation wins. Preferred’s variation between their 3 cylinders was an amazingly low 17 PSI.
