    摘要: A cementitious composition comprising hydraulic cement, not more than 25% of water by weight of the composition, and water soluble or dispersible (co)polymer in a proportion of 1 to 15% by weight of the hydraulic cement in the composition, the cement and (co)polymer being selected such that a test composition comprising 100 parts by weight of cement, 5 parts by weight of (co)polymer, and 16 parts by weight of water when extruded in a capillary rheometer undergoes an increase of at least 25% in shear stress when a ten-fold increase in the shear rate of the test composition from the capillary of the rheometer is effected. Also a cementitious product produced by setting of the composition. The (co)polymer is preferably a partially hydrolyzed poly (vinyl acetate). The cementitious product may have a flexural strength in excess of 100 MPa.
