Slag powder is mainly used in the field of construction engineering, and national policies promote the acceleration of the development of the industry
Slag powder, also known as granulated blast furnace slag powder, is an industrial by-product, which refers to the fine powder made by deep processing of slag produced in the smelting process of various metals. Slag powder has the advantages of low production cost, green environmental protection, high activity, large specific surface area, good durability and high strength, and is widely used in construction engineering, environmental protection, agriculture and other fields.
In recent years, the state attaches great importance to the development of recyclable waste industries such as slag powder, and has introduced a number of encouraging policies. In February 2024, the General Office of the State Council issued the "Opinions on Accelerating the Construction of a Waste Recycling System", which clearly proposes to promote the recycling of waste in various fields, and by 2025, the annual utilization of bulk solid waste such as fly ash, tailings, construction waste, and smelting slag in the mainland will reach 4 billion tons. In the future, with the support of national policies, the development speed of the slag powder industry in mainland China is expected to accelerate.
The main raw material of slag powder is pig iron waste slag. The mainland is a major steel producer, and its output has been the world's leading for many years. According to statistics from the China Iron and Steel Association, the mainland's pig iron output will reach 871.01 million tons in 2023, a year-on-year increase of 0.7%. 1 ton of pig iron will produce 0.3 tons of slag during the smelting process. With the increasing demand for steel applications in mainland China, the output of industrial wastes such as slag continues to grow, which will bring opportunities for the development of the slag powder industry.
According to the "2024-2029 China Slag Powder Industry Market In-depth Research and Development Prospect Forecast Report" released by the Xinsijie Industry Research Center, slag powder has broad application prospects in many fields, and the construction engineering field is its largest demand side. Slag powder can be added to concrete as admixture and admixture, which can effectively improve the anti-seawater corrosion performance of concrete and the reaction performance of alkali aggregate. Benefiting from the accelerated development of the downstream industry, the market space of slag powder in mainland China will be further expanded.
There are many slag powder production enterprises in mainland China, and the market competition is fierce. Luchang Technology, Luxin New Materials, Sanchuang Environmental Protection, Liugang Co., Ltd., Tengxin Building Materials, Xinrun Tongchuang, Saikeruisi, Zhengkang New Materials, Zhongtian New Materials, Changshengyuan, etc. are the main participants in the slag powder market in mainland China. According to its annual report, the company's sales volume of slag powder will reach 731,000 tons in 2023, and the output will reach 736,000 tons.
Industry analysts said that as an industrial by-product, slag powder has broad application prospects in the field of construction engineering, and its industry development space will be expanded with the gradual release of market demand in the future. In recent years, benefiting from the support of national policies, the development speed of the slag powder industry in mainland China has been accelerating. In terms of market competition, there are many slag powder production enterprises in mainland China, and Luchang Technology, as a representative enterprise, ranks among the leading companies in the industry in terms of product sales.
