Combining the Zheng-Xi＇ an passenger line Xi＇ an North station building engineering, the durability of the high performance concrete are studied. Study proves, through the selection of raw materials and the design of the optimization, using high quality and highly efficient and mineral admixtures mixing with families, water consumption and the dosage of cement is reduced, the resistance of concrete chloride permeability, crack and the frost resistance are improved, and a limit of raw materials and alkali content of chlorine ion in concrete measures are taken to prevent alkali aggregate reaction and rust corrosion, to ensure the durability of concrete passenger special line.
