Abstract：A type of anti-swelling grouting material has been manufactured in order to meet the demand for the grouting reinforcement of the underground roadway in swelling soft rock. The main parameters of performance of the grouting material，such as the density，the bleeding ration，the setting time，the fluidity and the consolidating strength were studied in the laboratory tests. Meanwhile the reinforcement performance of the grouting material was researched in an in-suit experiment. The results show that the main parameters of performance of the grouting material are optimal when the water-cement ratio is 0.5：1 and the ratio of the additive is 5‰. The grouting material is confirmed to improve effectively the property of the surrounding rock and enhance the strength of the broken and swelling soft rock. Meanwhile the grouting material also prevents the swelling deformations of the soft surrounding rock during the grouting process.
