Problems solved by technology

[0003] In addition, during the mechanized production of the factory, the cut aerated concrete blocks are stacked together, and then sent to the autoclave for autoclaving. At this time, the autoclaved effect of the aerated concrete blocks in the middle of the stack It will inevitably be affected, and the aerated concrete blocks in the middle of the pile are not qualified due to insufficient autoclave, resulting in waste

Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0054] refer to Figure 1 to Figure 8 , in one embodiment of the present invention, a kind of vanadium smelting slag is provided to produce aerated concrete block and its preparation method, and its formula consists of

[0055] Basic raw materials: 40% to 50% of vanadium smelting slag, 20% to 30% of silica sand, 8% to 15% of quicklime, 3% to 5% of gypsum, and 8% to 15% of cement, and the percentages mentioned are percentages by weight;

[0056] Additives: based on 100% of the basic raw materials, the aluminum powder is 0.8-1.2‰ of the basic raw materials, and the washing powder is 0.05-0.1‰, and the stated percentages are percentages by weight;

[0057] The solvent may be water, and the water-to-material mass ratio of the water to the basic raw material is 0.6-0.7.

[0058] In one embodiment of the present invention, choose vanadium smelting slag 40...

Abstract

The invention discloses an aerated concrete block produced from vanadium smelting slag. The formula includes: basic raw materials, 40-50 parts of vanadium smelting slag, 20-30 parts of silica sand, 5-15 parts of quicklime, 3-5 parts of gypsum, 8-15 parts of cement; additives, aluminum powder and washing powder, the aluminum powder is 0.5-1.2‰ of the total mass of the basic raw materials, and the washing powder is 0.05-0.1‰ of the total mass of the basic raw materials; solvent , is water, and the water-to-material mass ratio of the water to the basic raw material is 0.6-0.7. It can consume more vanadium smelting slag, and has a good effect on waste utilization, energy saving and environmental protection. The produced vanadium smelting slag produced aerated concrete blocks has good compressive strength, crack resistance and radiation protection. Also provided is a preparation method for producing air-entrained concrete blocks from vanadium smelting slag, which has a simple process and high-quality finished products.

Description

technical field [0001] The invention relates to the field of aerated concrete blocks, more specifically, it relates to an aerated concrete block produced from vanadium smelting slag and a preparation method thereof. Background technique [0002] The aerated concrete block is mainly made of fly ash, lime, cement, gypsum, slag, etc., adding an appropriate amount of air-generating agent, regulator, and air bubble stabilizer. A porous concrete product made by other processes. There are many ways to choose which kind of air generating agent, regulator or air bubble stabilizer, and it has a great influence on the performance of the finished air-entrained concrete block. [0003] In addition, during the mechanized production of the factory, the cut aerated concrete blocks are stacked together, and then sent to the autoclave for autoclaving. At this time, the autoclaved effect of the aerated concrete blocks in the middle of the stack It will inevitably be affected, and the aerated...
