Diatomite fillers are composed of hydrated amorphous silica and are essentially inert. One exception is that the natural uncalcinedgrades are extremely readtive to alkalies. Several uses have been made of this property , it's high reactivity has been used to control deleterious effect occuring when high alkalie portland céments are combine with reactive aggregates such as lime stone.
For improving compressive and tensile strength of cement as addition of only 3% of Diatomite in their final grinding can help them to improve the strenth.
In cement products ,such as in manufacturing precast cement pipes and blocks as well as various other cement products ,when only small percentage of Amorphous Silica is mixed it can reduce the use of cement equivalant to nearly four times the material added which can bring in substantial economy and added value such as fire proof,light weight and better smooth finish.
This is the product which is substatially used in western countries in various construction jobs as well as in the production of cement base products.
