Abstract
A cementitious composition comprising (a) at least one hydraulic cement, (b) water, (c) at least one polymeric water-soluble or water-dispersible additive which is capable of aiding in the processing of the composition, and (d) at least one particulate material insoluble in the composition and having an ultimate particle size of less than 0.1 micron, and a cement product produced therefrom.
Claims12
A cementitious composition comprising:
- (a) at least one hydraulic cement,
- (b) water in an amount of not more than 25% by weight of said hydraulic cement,
- (c) at least one polymeric water-soluble or water-dispersible additive which is capable of aiding in the processing of the composition in an amount of 1 to 10% by weight of the hydraulic cement in the composition, and
- (d) at least one particulate material insoluble in the composition and having an ultimate particle size of less than 0.1 micron, in an amount of 0.5 to 10% by weight of the hydraulic cement in the composition.
