Contraction Joint in Concrete – Their Location and Construction
Contraction joints in concrete are provided at regular interval to from a weak plane, so that cracks are formed at the joints but not in undesired places. Contraction joints are provided in concrete pavements, slabs, walls, floors, dams, canal linings, bridge, retaining walls etc.
CONTRACTION JOINT IN CONCRETE – WHAT, WHY & HOW?
2016年2月15日 · A contraction joint is one in which the two concrete surfaces are free to move away from one another as a result of shrinkage or thermal movement. Relative movement in the plane of the joint is prevented.
Expansion Joints Vs Contraction Joints Vs Construction Joints!
Contraction Joints. It is another type of joint which controls the cracks happening due to shrinkages. The contraction joints are placed as a groove where the crack may form in concrete. If the shrinkage crack is formed in the concrete slab then the …
