Noun

1. {{lb|en|construction}} A weak, milky layer of [[cement]] and [[aggregate]] [[fines]] on a [[concrete]] surface that is usually caused by an [[overwet]] [[mixture]], [[overworking]] the mixture, improper or excessive finishing or combination thereof. Also, could be caused when a slurry mix is used on a deep foundation, where the slurry mix is not completely removed before placing concrete on top.
2. {{lb|en|construction}} The weak top layer of [[cement]] and [[aggregate]] [[fines]] on a [[concrete]] surface that stands between a topical coating and the underlying substrate. This laitance layer prevents a bond forming between the topical coating and substrate, whereby it causes delamination of the topical coating as the laitance layer fails first.
