Abstract
An uncured cementitious composition comprising in admixture: PA0 (a) at least one hydraulic cement; PA0 (b) at least one reactive water-soluble polymer which is capable of providing a viscous solution in water at low addition levels; PA0 (c) water in an amount of from 10 to 25 parts by weight of water per 100 parts by weight of the cement; and PA0 (d) a water soluble cross-linking agent capable of effecting chemical cross-links between molecules of the said polymer in the presence of the cement and water.
