Placing Joints in Concrete Flatwork- Why, How, and When

While concrete is very strong in compression the tensile strength is only 8 to 12 percent of the compressive strength. In effect, tensile stresses act against the weakest property of the concrete material. The result is cracking of the concrete. There are two basic strategies to control cracking for good overall structural behavior.
