The invention relates to a concrete accelerator with small stirring resistance. The concrete accelerator comprises the main components of bauxite, sodium carbonate and quicklime; the main components are mixed and fired into clinker, and the clinker is added with 15 to 20 parts of sodium nitrite, 15 to 45 parts of sulfuric acid, 15 to 20 parts of magnesium sulfate, and 5 to 10 parts of polyethyleneimine; the amount of sulfuric acid is preferably 35 parts. Compared with the prior art, the concrete accelerator has the beneficial effect that by adding the sodium nitrate, calcium lignosulphonate powder, the magnesium sulfate and the polyethyleneimine, the better effect is realized. 种搅拌阻力小的混凝土速凝剂，主要成分为铝矾土、纯碱、生石灰混合后烧制成的熟料，还加入了亚硝酸钠15-20份、硫磺酸15-45份，硫酸镁15-20份、聚乙烯亚胺5-10份。所述的硫磺酸35份。与现有技术相比，本发明所具有的有益效果为：本发明通过加入亚硝酸钠、木质素磺酸钙粉，硫酸镁、聚乙烯亚胺，使得该速凝剂具有很好的效果。
