Favored by dual factors of demand and policy, the development trend of the high-strength ceramsite industry is improving


Ceramsite refers to a lightweight aggregate produced by foaming in a rotary kiln. According to different strengths, ceramsite can be divided into two categories: ordinary ceramsite and high-strength ceramsite. According to the “Lightweight Aggregates and Their Experimental Methods” GB/T17431.1-2010 standard, high-strength ceramsite refers to light coarse aggregates with a strength rating of ≥25MPa.
High-strength ceramsite has the advantages of high apparent density, high strength, small porosity, low water absorption, good thermal insulation performance, strong earthquake resistance, good moisture resistance and anti-corrosion performance, etc. It is mainly used in construction, gardening, environmental protection and other fields. Among them, construction is the main application field of high-strength ceramsite. In this field, high-strength ceramsite is mainly used in the production of building materials such as concrete, blocks, boards, and bricks, and is further used in the construction of high-rise frame buildings and long-span buildings.
Under the current background of rapid development of the domestic construction industry, the market demand for high-strength ceramsite continues to increase, which in turn drives the output to continue to increase. According to the “In-depth Market Research and Investment Strategy Suggestions Report on High-Strength Ceramics Industry 2023-2028” released by the Industrial Research Center, in 2022 The annual domestic output of high-strength ceramsite is approximately 1.558 million square meters, a year-on-year increase of 11.4%. At the same time, high-strength ceramsite has become the preferred concrete aggregate for prefabricated buildings due to its good advantages. With the penetration rate of domestic prefabricated buildings increasing significantly, its demand has continued to grow, and the industry has broad prospects for development.
At present, the mainstream production path of high-strength ceramsite is to use decarbonized coal slime, engineering spoil, fly ash and other solid waste as raw materials, and generate high-strength ceramsite through mixing and granulation, drying, calcination, cooling and other links. High-strength ceramsite belongs to the solid waste comprehensive utilization industry, and the development of the industry is strongly supported by policies. For example, in January 2022, the state issued the “Implementation Plan on Accelerating the Comprehensive Utilization of Industrial Resources” which proposed to accelerate the extraction of valuable components from industrial solid waste such as tailings (co-associated mines), fly ash, and coal gangue. , large-scale utilization in fields such as , building materials production and other fields.
my country’s high-strength ceramsite industry started relatively late, and related products only appeared in the 1960s. However, in recent years, due to the favorable factors of demand and policy, the number of high-strength ceramsite companies in my country has continued to increase. The main companies include Guangzhou Ceramic Products, Junyeyuan Building Materials, Dongyao Building Materials, Haopan Energy Saving Technology, Jiashun Environmental Protection Technology, Everbright Ceramic products, Huiteng light aggregate, etc. Due to technical limitations, the current application of domestic high-strength ceramsite is still mainly concentrated in the field of low-strength non-load-bearing structures. Compared with advanced foreign products, there is a large gap between domestic products and foreign advanced products in terms of technology, quality, performance, etc. In the future, local companies will still need to accelerate technology improvement. level.
Industry analysts said that high-strength ceramsite is an important lightweight aggregate required in the construction field. It is currently used in the domestic construction and prefabricated construction industries. Driven by rapid development, its market demand continues to increase, and the industry shows good development prospects. At the same time, high-strength ceramsite also belongs to the solid waste comprehensive utilization industry, and its development is strongly supported by national policies. Overall, the current development of my country’s high-strength ceramsite industry continues to be favored by both demand and policy factors, and the overall development trend is positive.
