Abstract

The invention discloses a sintered brick prepared from manganese slag and a preparation method of the sintered brick. The sintered brick is prepared from, by weight, 100-150 parts of manganese slag, 60-80 parts of paper mill sludge, 5-10 parts of redispersible powder, 4-6 parts of rosin resin and 5-8 parts of boric oxide. According to the sintered brick, manganese slag and paper mill sludge serve as the main raw materials, an effective approach is provided for comprehensively utilizing solid waste, environment pollution is reduced, clay resources are protected, sustainable development is facilitated for human, and high economic value is achieved. The sintered brick has the advantages of being high in strength, low in water absorption rate, low in density, good in heat preservation and thermal insulation effect, wide in raw material source, low in cost, simple in preparation process, low in energy consumption and the like and has quite good market prospects.

Description

technical field [0001] The invention belongs to the technical field of new building materials, and specifically relates to a sintered brick made from manganese slag and a preparation method thereof. Background technique [0002] Manganese is an important basic material in the national economy and one of the country's important strategic resources. At present, my country has become the world's largest producer, consumer and exporter of electrolytic manganese. As an important metallurgical and chemical raw material, electrolytic manganese has made great contributions to my country's industrial development and regional economic construction. However, the electrolytic manganese industry, as a typical hydrometallurgical industry, has also caused serious environmental problems during its rapid development. Pollution, especially electrolytic manganese waste slag pollution, according to statistics, the amount of acid leaching slag discharged per 1 ton of electrolytic manganese powder...
