NOVELTY - Color decorative mortar comprises 100-200 pts. wt. white Portland cement, 400-650 pts. wt. quartz sand, 50-100 pts. wt. colored glaze, 30-50 pts. wt. silica fume, 15-40 pts. wt. re-dispersible latex powder, 2-4 pts. wt. starch ether, 2-3 pts. wt. cellulose ether, 2-5 pts. wt. charred wood fiber, 0.1-0.5 pt. wt. water repellent, 0.1-0.2 pt. wt. graphene oxide, 10-50 pts. wt. inorganic pigment and 30-50 pts. wt. perlite powder. The inorganic pigment is iron oxide yellow and iron oxide red at 3-7:2. The charred wood fiber is obtained by calcining the wood fiber. The graphene oxide has 10-100 nm size. The preparation of colored glaze sand comprises mixing ceramic solution and ceramic pigment at 70-80:1, adding water and co-solvent, ball milling, mixing glaze and basalt at 1:9-10 and calcining. USE - Color decorative mortar. ADVANTAGE - The mortar has high bonding strength, good tensile, compressive properties, no efflorescence and good color durability.
