▎ 摘　　要

NOVELTY - A nickel slag cement-based grouting material comprises 55-65 pts. wt., preferably 60 pts. wt. nickel slag sand, 6-15 pts. wt., preferably 10.5 pts. wt. nickel slag powder, 15-25 pts. wt., preferably 20 pts. wt. Portland cement, 10-12 pts. wt., preferably 11 pts. wt. silica fume, 10-15 pts. wt., preferably 12.5 pts. wt. hybrid nanoparticles, 3-5 pts. wt., preferably 4 pts. wt. 0.15 g/L graphene oxide solution, 1.5-2.5 pts. wt., preferably 2 pts. wt. expansion regulator, 1.3-1.7 pts. wt., preferably 1.5 pts. wt. polycarboxylic acid water reducer, 0.5-1.5 pts. wt., preferably 1 pt. wt. highly active titanium fluoride, 0.4-0.9 pt. wt., preferably 0.65 pt. wt. defoamer, 1.5-2.1 pts. wt., preferably 1.8 pts. wt. triisopropanolamine and 12-20 pts. wt., preferably 16 pts. wt. mixing water. USE - Nickel slag cement-based grouting material for prefabricated buildings. ADVANTAGE - The grouting material realizes the reuse of solid waste resources to a great extent, and at the same time, the introduction of hybrid nanoparticles, graphene oxide solution, highly active titanium fluoride, can significantly improve the mechanical properties and fluidity of the slurry. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of the nickel slag cement-based grouting material.
