01Overview
Ground Calcium Carbonate
Ground Calcium Carbonate (special for plastering gypsum) is an inert inorganic filler that enhances the workability of mortar, optimizes particle grading, and improves coating whiteness, thereby significantly cutting raw material costs. The recommended dosage is 15-30% for base-layer plastering gypsum, 8-20% for top-layer plastering gypsum, and 5-15% for lightweight gypsum mortar. It is advised to use 200-325 mesh grades; when the dosage increases, an appropriate amount of cellulose ether should be added to maintain optimal workability.
