A cold joint is an adhesion-adhesion deficiency that visibly occurs at the joining surfaces of these castings into different parts at different times. ACI Committees, Membership, and Staff have answered common questions on a variety of concrete related topics. What is the difference between a contraction joint, isolation joint, expansion joint, construction joint, and a cold joint? A. A cold joint in concrete is an area or surface with a structural discontinuity caused by the delayed concrete pouring between two layers of concrete.
Concrete continues to be a fundamental building material in modern construction. Therefore, the repair and rehabilitation of concrete elements are critical for maintaining infrastructure
