2021-9-2  The usual recommendation is for some form of movement joint to be created in a non-reinforced slab at a separation of approximately 30 times the slab thickness. So, for a 100mm thick slab, there should be some form of joint every 100mm × 30 = 3000mm = every 3.0-3.6m and, in a 150mm slab, 150mm × 30 = 4500mm = 4.5-5.4m.

2010-11-1  Joints are necessary in concrete structures for a variety of reasons. Not all concrete in a given structure can be placed continuously, so there are construction joints that allow for work to be resumed after a period of time. Because concrete undergoes volume changes—principally related to shrinkage and temperature changes—it can be desirable to provide joints and, thus, relieve tensile ...
