[0004] The Chinese invention patent with the publication number CN106045477A discloses a method for preparing nickel-iron slag sintered permeable bricks. In the patent, nickel-iron slag of different thicknesses and an alkaline activator are used to prepare permeable bricks that require sintering or autoclaving. The product has a water-permeable effect Very good, but sintering and autoclaving are required in the preparation process, and the process cost is high
The Chinese invention patent with the publication number CN105016690A discloses a method for producing concrete by using water-quenched ferronickel slag. The water-quenched ferronickel slag is dried, finely ground, and classified to obtain fine slag and coarse slag, and the fine slag is added to the fine slag. The activator is fully mixed, so that the fine slag is used as an auxiliary gel material to replace part of the cement after being activated by the activator, and the coarse slag is used as a fine aggregate instead of part of the sand for concrete preparation. Although the cementitious material in this patent is very effective, but Excessive cement needs to be added during the preparation process, which is less economical

Abstract

The invention provides a building material prepared from ferro-nickel slag and relates to the technical field of building materials. The building material contains powder raw materials, a water reducer and water. The building material particularly contains the following raw materials in percentage by mass: 50%-70% of the ferro-nickel slag, 10%-30% of mineral slag, 10%-30% of coal ash, 5%-10% of gypsum and 5%-10% of steel slag. By comprehensively utilizing solid waste such as the ferro-nickel slag and the mineral slag, the prepared building material is environment-friendly, high in strength andgood in performance. Meanwhile, a preparation method provided by the invention is simple and convenient and easy for large-scale production.

Description

technical field [0001] The invention provides a building material prepared from ferronickel slag, which belongs to the technical field of building materials. Background technique [0002] The rapid development of industrial technology and social economy has formed an industrial system of mass production, high consumption and waste. Continuously produced industrial waste occupies a large amount of land resources and pollutes the environment. With the adjustment of industrial policies and the improvement of environmental protection awareness, the resource utilization of industrial waste is regarded as the most effective way to deal with industrial waste. [0003] Ferronickel slag is a solid by-product produced in the process of pyro-smelting ferronickel with laterite nickel ore. For every ton of ferronickel alloy produced, 4-6 tons of ferronickel slag will be produced. Compared with metallurgical slags such as slag and steel slag, ferronickel slag has high magnesium oxide co...
