【 Building materials network 】The Lantern Festival is not over yet, and the Spring Festival is not over yet. Just after the 7-day holiday, Wang Yanmou, the former director of the State Building Materials Administration, solemnly appealed for the promotion and application of sulfur (iron) aluminate in marine engineering cement 。 On the one hand, the cement industry is required to fully understand the importance of choosing seawater resistant cement concrete materials for modern marine engineering, and try to provide corresponding cement products; On the other hand, please ask the relevant government departments door Teams shall be organized to use and cooperate with the production units to promote the application of sulfur (iron) aluminate cement.

(The picture comes from the network and is deleted.)

At the end of last year, Wang Yanmou wrote an article on "the great rejuvenation of China's cement industry" to commemorate the 40th anniversary of reform and opening up. It is mentioned that sulphoaluminate cement has been successfully used in winter construction of housing construction; Urban overpass project; Underground waterproofing works; Urgent repair works of airport, highway, railway and other transportation facilities; oceanographic engineering; Concrete products And the fabrication of prefabricated components. In application, sulphoaluminate cement has accumulated a good durability record of 30-40 years, which has created very favorable conditions for its further development. It is predicted that in the new era of socialist construction, sulphoaluminate cement has great development potential. This kind of cement has seawater erosion resistance and frost resistance that Portland cement cannot match, and is a better choice for cement materials required in marine engineering construction, including the Arctic Ocean. China is the only country in the world with sulphoaluminate cement industry and national standard for sulphoaluminate cement.

In addition to the incomparable seawater erosion resistance and frost resistance of Portland cement, the sulphoaluminate cement has also made a major breakthrough in production. It has changed the history that only dry process hollow kilns were used in the past (the Catalogue for the Guidance of Industrial Restructuring makes an exception for the use of backward equipment), Yaobai Group cooperated with the Technical Information Research Institute of Building Materials Industry in production and technology development, and successfully trial fired sulfur (iron) aluminate cement clinker on 3200t/d precalciner kiln. What's more gratifying is that compared with Portland cement clinker, it can save 31% coal, reduce CO2 by 230%, reduce NOx by 70%, and achieve zero SO2 emission. In other words, its production is more green. This has laid a foundation for expanding the supply of sulphoaluminate cement.

There is an idiom "suit the remedy to the case", which means taking measures to solve problems according to the actual situation. Cement is an indispensable building material for construction projects, which is directly related to the quality of construction projects and is a major event in a century. For the cement industry, users need cement. Cement enterprises should not only sell cement, but also help users to propose reasonable solutions according to their use environment and conditions in the spirit of responsible service. For users of offshore engineering, it should be recommended to use sulphoaluminate cement with better seawater corrosion resistance. Even if they do not have the conditions to produce such cement for the time being, they should recommend enterprises that can produce sulphoaluminate cement. At the same time, we should carefully predict the market potential of sulphoaluminate cement, combine our own conditions, or make the decision of transformation or increasing technical reserves, to deal with the huge market potential of sulphoaluminate cement.

The promotion and application of sulfur (iron) aluminate cement is not a simple way to sell sulfur (iron) aluminate cement, but a "symptom" be launched Mud. What is cement for "disease"? This is what kind of cement enterprises propose more reasonable solutions for users according to the actual environment and conditions of using cement. This is responsible for users, construction quality and society, which is also necessary for the sustainable and healthy development of the cement industry!
