Special cement development report during the 13th Five-Year Plan period

Special cement refers to cement that has some special properties or special functions compared with general cement and aims to meet the special needs of engineering construction in various industries, and is known as the "pearl on the crown" of cement. Its birth has greatly expanded the application range and level of cement products, and is an indispensable basic material for major domestic projects. The development of special cement is also an important embodiment of China's cement industry to promote supply-side structural reform, achieve high-quality development goals, cultivate new momentum for industry development, and enhance the level of scientific and technological innovation in the industry. The application of multiple varieties of high-quality special cement has helped the construction of major national projects and provided a strong support for guaranteeing the construction progress and quality of projects.

I. National demand and industry policy during the 13th Five-Year Plan period

According to the Outline of the 13th Five-Year Plan for National Economic and Social Development released in 2016, various ministries and commissions and regions across the country have put forward corresponding 13th Five-Year plans. Such as the "13th Five-Year Plan for National Science and Technology Innovation", "13th Five-Year Plan for National Marine Economy", "13th Five-Year Plan for Western Development", "13th Five-Year Plan for National Strategic Emerging Industry Development", "13th Five-Year Plan for Energy Development", "13th Five-Year Plan for Modern Comprehensive Transportation System Development" and so on.

In June 2017, the "13th Five-Year" development Plan for the cement industry released by the China Cement Association also clearly stated that: accelerate product upgrading and extend the cement industry chain.

It mainly includes:

1) Eliminate composite 32.5 cement, encourage the production and use of 42.5 and above grade cement, and give priority to the development of special special cement (Marine, port, nuclear power, road and other projects).

2) Promote chromium-free refractories, long-life new refractories, and high-efficiency thermal insulation materials with microporous structures.

3) Accelerate the development of sand aggregate, high-performance mixed concrete, ready-mixed mortar and concrete products and other industries to extend the cement industry chain.

These policies lead the variety innovation of special cement, promote the high-quality development of special cement, and play an important role in accelerating the implementation of major engineering projects, implementing the new development concept, promoting the supply-side structural reform, and achieving the steady growth of special cement, adjusting the structure and making up for shortcomings.

2. Innovation and high-quality development of special cement

The definition of special cement is classified according to the outstanding performance or use of special cement, so there is a certain degree of limitation in the application of special cement due to the lack of understanding of the performance of special cement in the market.

The 13th Five-Year Plan involves a number of major projects, such as: the operating mileage of high-speed railways has reached 30,000 kilometers, covering more than 80% of big cities; About 30,000 kilometers of newly built or upgraded expressways are open to traffic. Construction of Sichuan-Tibet railway and other border railways; Beijing's new airport will be completed, and more than 50 new civil transport airports will be built. We will renovate and build a million kilometers of rural roads. Vigorously promote the development of Shanghai, Tianjin, Dalian, Xiamen and other international shipping centers; We will raise the level of port intelligence. We will build urban agglomeration transportation circles, and increase the operating mileage of urban rail transit by about 3,000 kilometers.

Construction of 60 million kilowatts of conventional hydropower began; The installed capacity of nuclear power plants in operation will reach 58 million kilowatts, and those under construction will reach more than 30 million kilowatts. Promote exploration and development of tight oil, oil sands, deep-sea oil and comprehensive development and utilization of oil shale; Construction of hydropower bases and large coal power base external power transmission channels. Construction of a number of major water diversion projects, such as the Yellow River to Budian Lake, the Yangtze River to Huaihe River, the Han River to Wei River, the central Yunnan River to Huang River, the Chuo River to Liao River. Promoting the follow-up construction of the East-Central Route of the South-to-North Water Diversion Project; The construction of Laluo in Tibet, Zhuxi in Zhejiang, Huokou in Fujian, Fengfeng in Heilongjiang, Mangshan in Hunan, Agang in Yunnan and other large reservoirs; Construction of river basin control hub projects such as Xijiang Dateng Gorge, Huai River Outlet and Xinjiang Altashe; We have basically managed 244 major rivers with a drainage area of 3,000 square kilometers or more. We will build 50 industrial bases for the comprehensive utilization of industrial waste, and discharge all industrial pollution sources up to standards.
