Embodiment 1

[0022] Embodiment 1: Take by weighing electrolytic manganese slag 50kg, fine aggregate (sand) 32kg, cement 15kg, quicklime 2.5kg, gypsum 0.5kg and water 7.1kg, wherein quicklime and gypsum are the product after grinding through 80 mesh sieve respectively, Add water into the forced mixer, and add the rest of the raw materials while stirring according to the order of electrolytic manganese slag, sand, quicklime, gypsum, and cement. The formed electrolytic manganese slag hollow block was cured in a 1 MPa autoclave for 10 hours to obtain the electrolytic manganese slag hollow block.

Embodiment 2

[0023] Embodiment 2: Take by weighing electrolytic manganese slag 45kg, fine aggregate (sand) 35kg, cement 17.5kg, quicklime 2kg, gypsum 0.5kg and water 7.0kg, wherein quicklime and gypsum are the product after grinding through 80 mesh sieve respectively, First mix cement, quicklime and gypsum evenly, add water to the mixer, then add electrolytic manganese slag to the mixer and stir for 2-10 minutes, add sand and stir for 2-5 minutes, add cement mixture and stir for 2-8 minutes, mix well and put it into the hollow In the block mould, pressurization is used to form, and then the formed electrolytic manganese slag hollow block is cured for 28 days under natural conditions above 5°C to obtain the electrolytic manganese slag hollow block.

Embodiment 3

[0024] Example 3: Weigh 55kg of electrolytic manganese slag, 30kg of fine aggregate (sand), 13.5kg of cement, 1.3kg of quicklime, 0.2kg of gypsum and 6.0kg of water, wherein the quicklime and gypsum are respectively ground and passed through an 80-mesh sieve. First, mix cement, quicklime and gypsum evenly, add water to the mixer, then add electrolytic manganese slag to the mixer and stir for 2-10 minutes, add sand and stir for 2-5 minutes, add cement mixture and stir for 2-8 minutes, and put it into the In the hollow block mould, it is formed by pressurization, and then the formed electrolytic manganese slag hollow block is cured in a 0.8MPa autoclave for 12 hours to obtain the electrolytic manganese slag hollow block.

Abstract

The invention discloses a hollow building block manufactured from electrolytic manganese residues and a manufacture method thereof. The hollow building block is manufactured from the electrolytic manganese residues, fine aggregate, cement, quick lime, gypsum and water. In the invention, solid wastes, namely the electrolytic manganese residues are utilized to manufacture the hollow building block which is strongly popularized in China. The obtained hollow building block has the advantages that the strength is up to 5-25 MPa, the hollow ratio is larger than 25%, and the content of the electrolytic manganese residues is higher than 40%. The method provided by the invention can be favorable for solving the problems of environmental pollution, land resource waste and like caused by the electrolytic manganese residues, and sufficiently exerting the efficacy of the electrolytic manganese residues.

Description

technical field [0001] The invention relates to the technical field of hollow blocks, in particular to a hollow block prepared by electrolytic manganese slag and a preparation method thereof. Background technique [0002] At present, the country is banning the use of solid clay bricks, vigorously promoting building wall materials such as hollow bricks, unburned bricks, and energy-saving bricks, and vigorously advocating the rational use of industrial solid waste. There are more than 50 million tons of electrolytic manganese slag in my country, and the amount is increasing by more than 10 million tons per year. Therefore, rational use of electrolytic manganese slag to produce hollow blocks can not only effectively utilize industrial solid waste, but also save national resources and energy. [0003] Electrolytic manganese slag is the solid waste left after rhodochrosite is treated with sulfuric acid solution to produce manganese metal. The concentration of sulfate, ammonia ni...
