Aerated concrete block produced from vanadium smelting slag and preparation method thereof

Abstract

The invention discloses an aerated concrete block produced from vanadium smelting slag. Tthe formula of the aerated concrete block comprises the following components: raw materials: 40-50 parts of vanadium smelting slag, 20-30 parts of silica sand, 5-15 parts of quick lime, 3-5 parts of gypsum and 8-15 parts of cement; additives: aluminum powder and washing powder, wherein the aluminum powder accounts for 0.05-0.12% of the total mass of the basic raw materials and the washing powder accounts for 0.05-0.01% of the total mass of the basic raw materials; and solvent: water, wherein the mass ratioof the water to the water material of the basic raw materials is 0.6-0.7. The method can consume more vanadium smelting slag and has good effects in the aspects of waste utilization, energy conservation and environmental protection, and the aerated concrete block produced from the produced vanadium smelting slag has good compressive strength, crack resistance and radiation resistance. The invention further provides a preparation method for producing the aerated concrete block from the vanadium smelting slag. The process is simple and the finished product quality is high.

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...

[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
