▎ 摘 要
NOVELTY - A composite additive comprises 100-150 pts. wt. kaolin, 3-5 pts. wt. hydrophobic cellulose ether, 1-3 pts. wt. graphene oxide, 2-5 pts. wt. tartaric acid, 2-5 pts. wt. water reducing agent, and 5-10 pts. wt. organosilicon water repellent. USE - Composite additive for common waste concrete mortar material (claimed). ADVANTAGE - The additive has low cost, mortar tensile cohesional strength, and high compressive strength.
