The invention discloses anti-crack concrete which comprises the following raw materials in parts by weight: 300-400 parts of ordinary Portland cement, 700-800 parts of crushed stone, 500-600 parts of river sand, 200-300 parts of mica powder, 3-5 parts of a novel water reducing agent, 30-40 parts of rice hull powder, 100-200 parts of furnace dust, 3-4 parts of calcium stearate, 6-10 parts of nano silica, 3-4 parts of aluminum dihydrogen phosphate, 6-10 parts of polypropylene powder, 2-3 parts of metaboric acid, 20-30 parts of calcined conch shell powder and 160-200 parts of water. According to the anti-crack concrete, since the novel water reducing agent is added, the flowability of the concrete is improved, a water reducing effect is enhanced, and freeze-thaw resistance of the concrete is improved; since the polypropylene powder, the furnace dust and an aluminum adhesive solution are mixed, dispersity of the polypropylene powder and the furnace dust in slurry is improved, and toughness, impact resistance, durability and crack resistance of the concrete are improved.
