CAAL has been working with LADOTD through the Technical Committee to revise the specification requirements for dense concrete.  The new requirement will be SR of 18 at 28 days as compared to 22 at 28 days.  This represents a major accomplishment for the concrete industry in its ability to meet project level specifications. Everyone who participated can take credit for working this issue.  A special thanks to Tyson Rupnow at LTRC for his knowledge and persistence in getting this done through LADOTD.
