The invention relates to anhydrous stemming, which is composed of a fireproof mixture and a composite binder. Based on the total weight of the fireproof mixture, the fireproof mixture comprises: 10-45% of alumina, 8-20% of silicon carbide, 0-30% of coke, 0-20% of clay, 0-8% of modified asphalt, 4-6% of kyanite, 2-6% of sericite, and 1-3% of silicon metal powder. The composite binder is composed of tar and grease with a weight ratio of (9-9.5): (0.5-1). The mass ratio of the fireproof mixture to the composite binder is 100: (13-20). The anhydrous stemming is excellent in plasticity, easy to open, and low in material consumption.
