FIELD: building materials.
SUBSTANCE: invention relates to a chrome-containing hydraulic binding agent. Hydraulic binding agent comprises cement as a main component and a mixture consisting of a chromate reducing agent and a carrier wherein chromate reducing agent comprises two components of iron (II) sulfate wherein the first component represents a salt from filter in manufacturing titanium dioxide and the second one represents a green salt. Also, acidity regulating agent is added to a chromate reducing agent. Invention provides preparing the economy hydraulic agent exerting the content of soluble chromates that is lower significantly as compared the permissible normal value and possessing the enhanced stability against aging in prolonged storage.
EFFECT: improved and valuable technical properties of binding agent.
