Diatomite Its Characterization Modifications And

Diatomite (SiO 2 _nH 2 O) or diatomaceous earth is a pale-colored, soft, lightweight sedimentary rock composed principally of silica microfossils of aquatic unicellular algae. Diatomite consists of a wide variety of shape and sized diatoms, typically 10-200 mm, in a structure containing up to 80-90% voids (Lemonas, 1997).

Diatomite and Diatomaceous Earth Geology

Diatomite And Diatomaceous Earth Geology

Diatomite is often used as an additive in the manufacture of portland cement. High-quality diatomite contains over 80% silica, and it is added to the cement-making process to boost the silica content of the product. Diatomite straight from the mine is crushed and blended with the limestone, shale, or other materials being used to make the cement.
