The invention relates to a sleeve grouting material for steel bar connection in winter construction. Calcium nitrate and/or sodium thiocyanate are/is used for reducing the freezing point of the sleevegrouting material for steel bar connection, and the use amount of the nitrate and/or sodium thiocyanate accounts for 0.1-1.0% of the total mass of the sleeve grouting material. By reducing the freezing point of a slurry pore solution, a hydration reaction of a cemented material at a negative temperature is ensured. The sleeve grouting material for steel bar connection in winter construction develops rapidly in early strength in winter under a low temperature condition, is high in later strength, is well matched with a steel bar sleeve, and can at least meet the use of sleeve grouting for steel bar connection in winter under a -10 DEG C condition.
