NOVELTY - High strength grouting material comprises 2-20 pts. wt. sulfur aluminate cement, 15-30 pts. wt. superfine steel slag micro powder, 5-30 pts. wt. superfine mineral reinforcing material, 0.05-0.25 pts. wt. single-layer graphene dispersion, 10-20 pts. wt. quartz sand, 15-30 pts. wt. machine-made sand, 0.1-0.5 pts. wt. thickening agent, 2-6 pts. wt. water reducing agent and 0.1-0.5 pts. wt. expansion agent, where the single layer of graphite dispersion in the alkene is 5-20 wt.%. USE - Used as high strength grouting material. ADVANTAGE - The grouting material has rapid development of early strength, continuous increase of late strength, good initial fluidity, strong rebar gripping capability, and can play the role of detailed expansion in the early three hours, and does not shrink in the later period. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparing high-strength grouting material.
