| description | The invention provides a high-content coal gasification furnace slag-based green low-carbon cementing material and a preparation method thereof, and the method specifically comprises the following steps: burning 50-55% by mass of coal gasification furnace slag at 600-800 DEG C for 30 min, and cooling to room temperature, S2, mixing 50-55% by mass of coal gasification furnace slag after high-temperature burning, 15-20% by mass of slag and 17-20% by mass of gypsum according to a mass ratio of 1: (1-2), and carrying out stirring and mixing to obtain the high-content coal gasification furnace slag-based green low-carbon cementing material. And levigating 5% of furnace slag, 3%-4% of calcium hydroxide and 1%-2% of silica fume, and putting the levigated materials into a stirrer for mixing to obtain the high-content coal gasification furnace slag-based green low-carbon cementing material. The optimal crystalline phase structure of the coal gasification furnace slag is obtained through high-temperature firing tempera |
