The invention discloses low-alkali concrete which comprises components in parts by weight as follows: 100 parts of cement, 50-60 parts of water, 150-250 parts of sand and 5-8 parts of a concrete modifier, wherein the concrete modifier comprises components in parts by weight as follows: 5-15 parts of calcium powder, 1-5 parts of calcium lignosulphonate powder, 4-8 parts of silicon dioxide powder, 2-6 parts of dispersible emulsion powder and 20-40 parts of coal ash powder. The concrete modifier is added to the low-alkali concrete, so that the low-alkali concrete has high bonding capacity and excellent antifreeze and anti-erosion capacity and can be widely applied to northern cold regions and saline-alkali regions.
