NOVELTY - Preparation of graphene oxide-reinforced cement grinding agent involves adding 1.5 g sodium nitrate, 3 g graphite powder and 70 mL concentrated sulfuric acid into flask, stirring at 300 revolutions/minute under ice bath condition, slowly adding 10 g potassium permanganate, stirring for 5 minutes, water reacting at 35 degrees C for 2 hours, slowly adding 150 mL deionized water, heating to 98 degrees C for 2 hours, cooling, adding 500 mL deionized water and 15 mL 30% hydrogen peroxide solution, standing for 24 hours, ultrasonically dispersing, centrifuging, filtering, repeatedly washing, and drying. USE - Method for preparing graphene oxide-reinforced cement grinding agent (claimed). ADVANTAGE - The grinding agent uses easy to obtain raw materials, good product performance, improves desktop bench production and mechanical properties, and is environment-friendly.
