Abstract:
When building a new headquarters for his concrete contracting company, the author decided to make the slab for the warehouse a working showplace. Using a concrete mixture that contained a high volume of large maximum size coarse aggregate to reduce shrinkage and macro polymeric synthetic fibers to help minimize plastic and drying shrinkage cracking, the joint spacing for the 6 in. (150 mm) thick slab was pushed to a 25 ft x 20 ft 10 in. (7.6 x 6.4 m) grid. Even after a year in service, the slab has an overall average FF 48/FL 38.
