▎ 摘　　要

NOVELTY - Mortar composition comprises 5-10 pts. wt. loess, 10-20 pts. wt. artificial aggregate made of 10-20 pts. wt. sand, 0.015-0.025 pts. wt. graphene powder, 5-15 pts. wt. photocatalyst powder, and 1-2 pts. wt. high-performance water reducing agent and pulverized into 60-150 mesh. The photocatalyst is titanium dioxide including anatase and/or rutile, and the artificial aggregate contains 1-5 pts. wt. silica fine powder, 1-5 pts. wt. expanding agent, calcium sulfur aluminate, anhydrous gypsum, quicklime, and cement powder, 0.1-1 pts. wt. cellulose-based or polysaccharide-based thickener, and white cement, 5-10 pts. wt. polymer including polyvinyl alcohol, carboxyl methyl cellulose, and hydroxy ethyl cellulose, calcium sulfur aluminate, anhydrous gypsum, quicklime, cement powder, zirconium oxide, cerium oxide, zinc oxide, iron oxide, chromium oxide and/or 1-5 pts. wt. colorant. USE - The composition is useful for interior and exterior of buildings. ADVANTAGE - The composition purify harmful substances; has high flexural strength and compressive strength, can decompose and remove pollutants, nitrogen oxides, sulfur oxides, and odor gases in atmosphere by photochemical reaction of photocatalyst; improves strength and durability of mortar construction site for long time and provides comfortable indoor space.
