Definition / notes:	Construction Joints Construction joints, unlike expansion and contraction joints, are no intended to allow for movement of concrete members, but generally are effected at the end of a lift, at the end of a day's concrete placement, etc. This type of joint is a plane surface between two sections of concrete-concrete placed against concrete already in place which has hardened to the extent that consolidation cannot be effected by vibration or re-vibration. Construction joints may be horizontal as in a structure or column, or vertical as in a slab, or both as in a wall. This type of joint is commonly termed as a "cold joint". Construction joint The contact between the placed concrete and concrete surfaces, against or upon which concrete is to be placed and to which new concrete is to adhere, that has become so rigid that the new concrete cannot be incorporated integrally by vibration with that previously placed. Unformed construction joints are placed horizontally or nearly horizontally.
