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.

Diatomite rock is a loose, earthy or loosely cemented porous and lightweight rock of sedimentary origin, mainly formed by fragments of armor (skeletons) of diatom algae: diatomea and radiolaria. Diatomite is a microscopic diatom alga whose size ranges from 0.75 to 1500 m; sometimes this rock is called infusorial earth, kieselguhr, or …
Diatomite samples were taken from the field and several tests were performed on natural diatomite samples. Hydraulic conductivity of natural diatomite was calculated as 10 −8 –10 −10 m/s. Apparent density of microscopically porous diatomite was 0.10–0.25 g/cm 3.For dry consolidated diatomite, densities were measured as …
