01Overview
White Portland Cement
White Portland cement serves as a key binding material for decorative gypsum and finishing mortars. It markedly enhances the hardness, whiteness, and density of surface layers while strengthening substrate adhesion and water resistance. With its rapid setting characteristics, it significantly reduces construction working time. The standard dosage ranges from 5-12% for decorative gypsum, 3-8% for finishing gypsum, and up to 5% for base gypsum. Proper formulation requires adjusting the proportions of water-retaining agents and retarders to ensure optimal construction performance and product quality.
