Abstract
Abstract A cementious composition is provided which comprises 25 to 100% Portland cement and from 0.001 to 0.25% of certain long-chain organic polymers having a Flocculation Index of less than 0.5. A dry-set grout composition may be prepared using the composition or a sag-resistant dry-set mortar compound may be prepared using the composition.
