During the “Eighth Five-Year Plan” period, the building materials industry in Xi’an was able to develop rapidly after large-scale technological transformation and external introductory incorporation. The total output value of building materials industry in the city reached 2.3 billion yuan, an increase of 158% over the “Seventh Five-Year Plan” and an average annual increase of 20%. As a result, the structural condition of building materials has been greatly improved and new optimization and upgrading are being realized. Over the past few years, the building materials companies in Xi’an have stepped up their technological transformation efforts. The number of renovation projects and the scale of transformation are 24 times that of the previous decade. Eight key cement companies in six districts and counties adopted the microcomputer-controlled pre-watering ball-forming technology and 14 new energy-saving technologies promoted by the country. The newly expanded production line generally adopts rotary kiln raw materials.
