A concrete expansion joint – or control joint – is a gap which allows the concrete to expand and contract as/when the temperature changes. It forms a break between the concrete and other parts of a structure to allow movement without causing stress, which can lead to cracking. • All concrete will shrink slightly as it dries and, when it’s set, will expand or contract depending on the ambient temperature. To prevent cracks from forming, concrete expansion joints should be incorporated to allow for movement, particularly in slabs with a surface area exceeding 6m2. • More information: • https://www.hanson.co.uk/en/ready-mix.... • http://www.builderbill-diy-help.com/c... • #concretecontroljoint #concrete #slab #sidewalk #architecture #civilengineering #civil #concretework #structure #concreteslab #building #masonry #road #highway #freeway
