▎ 摘　　要

NOVELTY - Graphene oxide modified raw soil-based material comprises 60-100 pts. wt. raw soil, 5-15 pts. wt. cement, 5-20 pts. wt. fly ash, 5-15 pts. wt. slag, 0.03-0.1 pts. wt. graphene oxide, 0.1-0.4 pts. wt. carboxylic acid water reducing agent, and 35 pts. wt. water. USE - Graphene oxide modified raw soil-based material. ADVANTAGE - The graphene oxide modified raw soil-based material is used to stimulate the hydration reaction of cement and mineral admixtures through graphene oxide, and have excellent mechanical properties and durability, and reduces shrinkage rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nano-modification method of graphene oxide modified raw soil-based materials, which involves: (A) weighing 0.03-0.12 pts. wt. graphene oxide powder or suspension according to the mass ratio; (B) adding 0.1-0.4 pts. wt. polycarboxylic acid water reducing agent and 35 pts. wt. water to the graphene oxide powder or suspension according to the mass ratio, stirring uniformly, and ultrasonically dispersing for 1-3 minutes to obtain a graphene oxide mixture; (C) weighing 60-100 pts. wt. raw soil, 5-15 pts. wt. cement, 5-20 pts. wt. fly ash, and 5-15 pts. wt. slag in the solid raw materials according to the mass ratio, and mixing them uniformly; (D) mixing the graphene oxide mixture with solid raw materials, mixing slowly for 3 minutes, and mixing quickly for 3 minutes; and (E) mixing graphene oxide mixed liquid and the solid raw materials fully uniformly to obtain the graphene oxide modified raw soil-based composite material.
