Much hematite occurs in a soft, finegrained, earthy form called red ochre or ruddle. Intermediate between these types are compact varieties, often with a reniform surface (kidney ore) or a fibrous structure (pencil ore). Red ochre is used as a paint pigment; a purified form, rouge, is used to polish plate glass.

Cement chemistry can affect the dispersion efficiency of superplasticizers in various ways. One of these is through the ionic composition of the aqueous phase and in particular through the amount of soluble sulfates. The milestone paper on this subject comes from Yamada and Hanehara (2001).As explained in Section on the reversibility of polymer adsorption, they made alternative additions
