COMPLEX ORGANIC ADDITIVE FOR INHIBITING ALKALINE CORROSION

摘要

FIELD: chemistry.SUBSTANCE: invention relates to the industry of construction materials and can be used in making concrete on an aggregate which contains active reactive silica. The complex organic additive contains superplasticiser S-3 and is characterised by that the superplasticiser S-3 is used in amount of 0.3% of the mass of cement and additionally contains citric acid in amount of 0.05% of the mass of cement.EFFECT: preventing reaction of alkali in the cement with silica in the aggregate and controlling longevity of the concrete mixture.1 tbl
