Cement Extender

CEMENT EXTENDERS manufactured by GDFCL are specialty Cementing additives that are used to decrease the density or increase the yield of the cement slurry. Materials with a specific gravity lower than that of the cement will act as cement slurry extenders.

GDFCL manufactures full range Cement slurry Extenders which can be customized and manufactured according to various customer needs such as varying temperature, Oil-well requirements and specifications.

Our research department has been working continuously to develop high performance Cement extenders to increase the yield of the cement and reduce costs and improve performance. 

Cement Slurry Extenders manufactured by GDFCL are divided into different categories:

Cement Extender Clays - Hydrous Aluminium Silicates having flaky shape and prominent cleavage.

Cement Extender Silicates - Calcium Silicate gel which provide sufficient viscosity to the cement slurry. They are available in liquid or powder form. 

Cement Extender Pozzolans- Silica and Aluminous material that contribute to the compressive strength of the set product .They are 2 types of pozzolans natural like volcanic ashes and artificial like fly ashes.

Cement Extender Lightweight Particales- Lightweight particle extenders that reduce the slurry density because they are lighter than the cement particles like specialised ignites and Gilsonites and other modified materials.

Cement Extender Microspheres- Range of Cenospheres by varying densities and glass microspheres of varying mesh sizes.
