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, an...

A body conforming absorbent article, such as a sanitary napkin, is disclosed which has preferential bending zones and a structural zone. The bending zones cause the article to preferentially bend at locations anterior and posterior to the labia majora so as to keep a relatively planar configuration in the perineal area. The structural zone is resistant to wet collapse so that the central portion o...
