Poor contact of the cold joint

A cold joint in concrete construction is a plane of weakness that forms when new, wet concrete is poured against concrete that has already begun to harden. This discontinuity occurs because the older material has passed its initial setting time, preventing a true chemical bond with. Cold joint concrete is a common problem in the construction world. If not...
