Abstract
A fiber-hydratable cement composition comprising a uniform dispersion of from 0.0001 to 10 volume percent interground fiber in hydratable cement powder is prepared by introducing fiber precursors and cement clinker to a grinding mill and grinding the mixture until the clinker has been reduced to a fine powder. The fiber can be steel, alkaline resistant glass, ceramic, carbon or organic polymer, and preferably are steel, polyolefin or mixtures thereof.
Claims19
A method for preparing an interground reinforcing fiber-hydratable cement composition comprising introducing at least one fiber precursor and cement clinkers to a grinding mill and grinding the mixture until the clinker has been reduced to a fine powder, the amount of the fiber precursor added being sufficient to yield from 0.0001 to 10 volume percent interground fiber in the ground product, wherein the fiber is selected from the group consisting of steel, alkaline resistant glass, ceramic, carbon, polyolefin, polyamide and mixtures thereof.
A fiber-hydratable cementitious composition produced by the process comprising introducing fiber precursors and cement clinkers to a grinding mill and grinding the mixture until the clinker has been reduced to a fine powder, the amount of fiber precursor added being sufficient to yield from 0.0001 to 10 volume percent interground fiber in the ground product.
A fiber-hydratable cement composition comprising a uniform dispersion of from 0.0001 to 10 volume percent of at least one interground fiber in hydratable cement powder, wherein the fiber is formed by grinding a fiber precursor with clinker to form a fiber-hydratable cement mixture, the fiber precursor being selected from the group consisting of steel, alkaline resistant glass, ceramic, carbon, polyolefin, polyamide and mixtures thereof.
