▎ 摘 要
NOVELTY - Grouting material comprises 40-60 pts. wt. cement, 2-8 pts. wt. fly ash, 40-60 pts. wt. quartz sand, 0.5-1.5 pts. wt. silicon dioxide gas gel, 0.01-5 pts. wt. graphene, 0.01-0.15 pts. wt. dispersant, 0.01-0.05 pts. wt. plastic expanding agent, 0.01-0.15 pts. wt. expansion agent, 0.01-0.1 pts. wt. antifoaming agent and 0.01-0.1 pts. wt. low viscosity cellulose. USE - The grouting material is useful for tunnel secondary lining. ADVANTAGE - The grouting material reduces hydration heat of the tunnel grouting layer. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparation method of grouting material for tunnel secondary lining. Method for reducing hydration heat of tunnel grouting layer.
