The invention belongs to cement auxiliaries and particularly relates to an alkaline-free liquid cement accelerator and a using method therefor. The alkaline-free liquid cement accelerator is prepared from the following components in parts by weight: 40-45 parts of aluminum sulfate, 5-10 parts of aluminum trifluoride, 0.2-0.5 part of a tackifying component, 4-9 parts of a reinforcing material, 3-7 parts of organic matters and 50-60 parts of water. The accelerator for a cement processing process provided by the invention has an adjusting effect on the cohesion time of cement, is free of corrosion and toxicity, causes no corrosive damages on the skin and body of constructors, and has no adverse influence on durability of concrete.
