Abstract:
Most slabs on grade curl. Some research has been done over the years to determine why slabs curl and how curling can be reduced or controlled. Unfortunately, because much of that work is so scattered, it hasn’t received the attention it deserves nor has it contributed to a better understanding of why slabs curl. Following is a summary of the research and what it may mean to designers, specifiers, and contractors.
