Containment systems for the prevention of pollution, Secondary, tertiary and other measures for industrial and commercial premises (CIRIA C736), published by CIRIA in 2014, suggests that construction joints (in concrete, sometimes referred to as daywork joints) refer to: ‘A joint in concrete construction formed when placement of the concrete is interrupted for some reason. It may be the end of the day’s work, or it may be that some other work needs to be completed before resuming the placement. Results in a ‘surface’ between freshly placed and (partly) cured concrete.’
Expansion joints (in concrete): ‘Allow expansion and contraction of a concrete slab or wall without generating potentially damaging forces within the slab itself or the surrounding structures. Expansion joints are usually a complete ‘gap’ between adjacent bays, ie there is a definite break in the concrete and reinforcing steel that may be present. Where adjacent bays are ‘tied’ together by means of dowel bars, these dowels are sleeved in one of the bays to allow expansion to take place without generating stresses within the slab.’
