Preparation technology and properties of ANS liquid low alkaline accelerator were introduced in this paper. Synergistic effect of different organic materials on accelerator system and the adaptability with different cements were test-ed. All results show that the adaptability of ANS liquid low alkaline accelerator is good, and it can guarantee the early and late compressive strength of cement mortar. This product has been used in shotcrete of Hafengjing tunnel in Hu-zhang railway, which achieved good effect in engineering.
