description	The invention discloses a high-performance composite grouting material for an assembled concrete structure. The high-performance composite grouting material comprises the following components in percentage by weight: 0.76-0.80% of Portland cement, 0.05-0.09% of sulphoaluminate cement with a water-binder ratio of 0.20-0.30 and a mortar-sand ratio of 1: 1, 1%-5% of a water reducing agent, 0.1%-0.5% of sodium gluconate, 0.02-0.08% of silica fume, 0.03-0.07% of slag, 0.04-0.06% of a CS expanding agent and 0.2%-0.6% of a defoaming agent. According to the invention, the early fluidity of the grouting material can be improved to a certain extent on the premise that the strength and the expansion performance of the grouting material are not changed, the construction operation time of the grouting material is shortened, a water consumption bandwidth is increased, and the grouting material is more suitable for actual engineering; the main performance indexes of the grouting material are that initial setting time is gre
