Is cold-jointing a good option

Sometimes it will be the best option rather than having a weak joint. In addition, special attention shall be made to forming cold joints in the concrete wall as it could lead to durability issues. 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 the fresh mix. If not handled correctly, it can weaken structures and shorten their lifespan. This article takes a closer look. There are different alternatives to deal with and repair cold joints, such as: The use of b...
