Abstract
Compositions and methods relating to cementitious compositions are provided. The use of a glucoheptonate in the alpha form to prolong the workability of cementitious compositions is provided. The alpha form of glucoheptonate (found to have properties superior to the beta form when used to retard the hydration of cementitious compositions) can be used in combination with a plasticizing resin, e.g. a naphthalenesulfonate/formaldehyde condensate resin, to prolong the workability of a cementitious composition, without unacceptably delaying green strength development. Also provided are mixtures of a glucoheptonate in the alpha form and a naphthalenesulfonate/formaldehyde condensate resin plasticizer.
