contraction joint

This allows large floor slabs (up to 60 m square) to be prepared without contraction joints.

Next, the concrete was settled with immersed vibrators and then contraction joints were cut into the layer.

Five feet separates each contraction joint - 3/8-inch-deep spaces that prevent cracks in one square, or flag, from spreading to another.

Along with innovative contraction joints, the Reclamation Service was able to control the temperature of the setting concrete, ensuring the dams strength.

JPCP's are constructed with contraction joints which direct the natural cracking of the pavement.

Structurally it's a relatively early example of an Ambursen-type dam, using contraction joints between all face slabs and buttresses for stability.

JRCP's are constructed with both contraction joints and reinforcing steel to control the cracking of the pavement.

To aide the release of this heat, engineers divided the dam into contraction joints and outfitted them with grout pipes and cooling coils.

Contraction joints are normally placed every 20 m in the arch dam and are later filled with grout after the control cools and cures.

Continuously Reinforced Concrete Pavements (CRCP) do not require any transverse contraction joints.
