Product Description
Gypsum is a naturally occurring mineral, chemically known as calcium sulfate dihydrate (CaSO4·2H2O). It appears as a white to grayish fine powder or crystalline solid. It is widely used in construction for plaster, wallboard, and cement manufacturing. In agriculture, gypsum improves soil aeration, water retention, and calcium content, enhancing crop yield. It also serves as an industrial filler and in various manufacturing processes. Zenco Systems Ltd provides high-quality gypsum across Kenya, Uganda, Tanzania, Rwanda, and other East African countries with strict quality control and competitive pricing. Proper storage in dry conditions and use of personal protective equipment while handling are recommended to avoid moisture absorption and dust inhalation risks.
