FIELD: construction.
SUBSTANCE: present invention relates to an additive for construction chemical compositions, particularly compositions of mortar and cement compositions. Additive includes at least one amide or sugar acid ester and at least one water-soluble comb polymer, which contains on the main chain acid functions and side chains having ether functions. Additive is useful for slowing down hardening of the building chemical composition. Also described is a construction chemical composition and use of an additive for slowing hardening of compositions of construction mixtures.
EFFECT: disclosed is an additive for construction chemical compositions.
