▎ 摘　　要

NOVELTY - A modified self-leveling mortar comprises phosphogypsum, common silicate cement, graphene oxide-based layered material, river sand, fly ash, hydroxypropyl methyl cellulose ether, water reducing agent, retarder and water. The graphene oxide-based layered material comprises organic matter as connecting substrate. The graphene oxide is used as layered material formed by substrate. The water reducing agent is polycarboxylate water reducing agent and the retarder is protein retarder. USE - Used as a modified self-leveling mortar. ADVANTAGE - The mortar has good fluidity, and excellent mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the modified self-leveling mortar.
