Abstract

The invention provides a method for preparing a construction material by utilizing electrolytic manganese slag, including the following steps: (1) pretreatment: additive is blended in the electrolyticmanganese slag, water is added for fully stirring, and the raw material reacts in the open air for 1-7 days, wherein the added additive is mixture of lime, plaster and kaolin; (2) cement, sandstonescoarse aggregate, sandstones fine aggregate and component selection air entraining agent are added into the electrolytic manganese slag after the pretreatment, water is added and blended evenly to form a mixture; (3) the mixture is loaded into a mould and formed on a compression forming machine by vibration and pressurizing, and then demoulding is carried out; (4) adobe is naturally cured for 14-28 days, thus obtaining the electrolytic manganese slag construction material product. The technique is simple with high product quality and low production cost and has good social, economic and environmental benefits.

Description

technical field [0001] The invention relates to a method for preparing building materials by electrolytic manganese slag, which belongs to the fields of resource recycling and environmental protection in the electrolytic manganese industry. Background technique [0002] "Without manganese, there is no steel." Manganese is an important foundation and strategic material of the national economy. Manganese products mainly include electrolytic manganese metal, manganese dioxide, manganese tetraoxide, and manganese sulfate. Among them, electrolytic manganese is the most widely used and has the largest output. It is widely used in high-tech fields such as steel and non-ferrous metal smelting, electronic batteries, aerospace, and national defense industries. With the development of science and technology, the application range of electrolytic manganese is increasing. Viewed, consumption is also increasing. [0003] In recent years, my country's electrolytic manganese industry has d...
