Embodiment Construction

[0019] A method for producing an aerated block doped with blast furnace slag, the method includes the following steps:

[0020] 1), after the fly ash, dihydrate gypsum and blast furnace slag are mixed and crushed, 12-19 parts of fly ash, 2-3 parts of dihydrate gypsum and 20-30 parts of blast furnace slag are taken in parts by mass;

[0021] 2) Take 10-15 parts of vanadium slag and 1-2.5 parts of aluminum powder in mass parts before fine grinding, and mix the crushed fly ash, dihydrate gypsum and blast furnace slag with vanadium slag and aluminum powder evenly After fine grinding, the crushed fly ash, dihydrate gypsum and blast furnace slag are evenly mixed with vanadium slag and aluminum powder, and the particle size of fine grinding is less than 20mm;

[0022] 3), crushing the crushed stones, and taking 12-25 parts by mass of the crushed stones;

[0023] 4), put the crushed crushed stones and the finely ground dry material into the mixing equipment, add water to fully stir,...

Abstract

The invention discloses a method for producing an aerated building block by using doping blast furnace slag. The method comprises the following steps: 1) mixing and crushing fly ash, dihydrate gypsum and blast furnace slag and weighing, by mass, 12 to 19 parts of fly ash, 2 to 3 parts of dihydrate gypsum and 20 to 30 parts of blast furnace slag; 2) before fine grinding, weighing 10 to 15 parts by mass of vanadium slag and 1 to 2.5 parts by mass of aluminum powder, uniformly mixing crushed fly ash, dihydrate gypsum and blast furnace slag with vanadium slag and aluminum powder and then carrying out fine grinding; and 3) crushing broken stone granules and taking 12 to 25 parts by mass of the crushed broken stone granules.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a method for producing aerated blocks by doping blast furnace slag. Background technique [0002] For a long time, the comprehensive utilization of blast furnace slag has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of blast furnace slag at home and abroad, most of them have not been implemented in industry due to various technical and economic reasons. [0003] In summary, there have been reports of using blast furnace slag as auxiliary raw material to produce cement, wall bricks, and road materials, but there has been no report of using blast furnace slag as the main raw material for the production of aerated blocks. Contents of the invention [0004] The purpose of the present invention is to provide a method of doping blast furnace slag to produce aerated blocks. The consumption of blast furnace slag is large, ener...
