The invention discloses concrete for a building bridge. The concrete is prepared from the following raw materials in parts by weight: 55-60 parts of cement, 20-30 parts of chromite sand, 10-12 parts of recycling sand, 3-4 parts of magnesium silicate, 6-8 parts of modified light calcium powder, 2-4 parts of argil, 0.4-0.6 part of methyl acrylate, 0.2-0.4 part of polymethyl methacrylate, 4-5 parts of titanium dioxide, 2-3 parts of calcium phosphate, 0.4-0.6 part of glass fiber, 0.3-0.5 part of cotton fiber, 0.8-1.0 part of triethanolamine, 0.2-0.5 part of polyimide, 2-4 parts of sodium silicate, 1.0-1.2 parts of sodium dodecyl benzene sulfonate and an appropriate amount of water. The concrete disclosed by the invention is simple in formula and can effectively prevent the bridge concrete from shrinkage cracks; the modified light calcium powder is mixed into the bridge concrete, so that no corrosion effect is generated to a reinforcing steel bar, the durability of a bridge building can be improved, the anti-impact energy consumption is greatly improved, and the service life of the concrete is prolonged.
