Flat slabs cold joints are arranged parallel to the smaller side of the product. Beams of significant sizes (they together with the slabs represent a monolith) HS are located in the zone, retreating 2-3 centimeters from the level of the lower surface of the slab. They miss the reality that a slab-on-grade demands a completely different. 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. The delayed placement prevents full integration and knitting between the concrete batches and might lead to reduced structural robustness, increased. Managing cold joints is an important concept to grasp when working on concrete projects. These happen when freshly mixed concrete is poured on top of a partially cured but already set layer.
