Gypsum is a critical input for Nigeria's cement sector and a growing commodity in agricultural soil improvement. Onsien supplies high-purity grades for both applications.

Gypsum serves as a retarder in Portland cement production, controlling the setting time of clinker and determining the workability of the final product. Every cement plant in Nigeria consumes gypsum as a standard additive.

Beyond cement, agricultural gypsum is used to improve soil structure on compacted or sodium-affected farmland. As Nigerian agriculture modernises, demand for soil amendment minerals is growing across the North and South-West.

Onsien Energy sources and supplies gypsum from active project areas, with both domestic delivery and export arrangements available under NEPC licence terms.

Applications
Where Our Gypsum Goes
Cement Retardation
Added during clinker grinding to control set time in Portland cement. Without gypsum, cement would set within minutes, making it unworkable on site.
Construction Plaster
Calcined gypsum (plaster of Paris) is used in wall plasters, plasterboard, and decorative mouldings across residential and commercial construction.
Agricultural Soil
Agricultural gypsum improves soil structure, provides calcium and sulphur nutrients, and reclaims sodic soils, increasing crop yield on affected farmland.
