Calcium Sulfoaluminate Cement

When hydrated, calcium sulfoaluminate cements form ettringite. a retarder which retards this reaction is at least one of phosphono alkyl carboxylic acid and a salt of a phosphono alkyl carboxylic acid. additionally, the retarder can comprise at least one of a carboxylic acid and a salt of a carboxylic acid. the retarder can be prepared as an admixture for addition to cement, or the retarder.
