Abstract

The invention discloses a barium residue coal ash building block and a productbulion method thereof. The barium residue coal ash building block is made in the manner that barium residue, coal ash, cement, water and an additive that is used for eliminating the toxicity of barium residue are taken as raw materials, and the raw materials are processed through metering, stirring and blending, compression moulding and stacking and maintaining; and the additive adopts soluble sulfate and slightly soluble sulfate. Desulfurized gypsum is used as the additive used for eliminating the toxicity of barium residue, and the raw material formula of the barium residue coal ash building block includes, by the mass proportion, 50 cement, 450 mountain sand, 400 barium residue, 100 coal ash, 50 desulfurized gypsum and appropriate amount of water; and sodium sulfate is used as the additive for eliminating the toxicity of barium residue, and the raw material formula of the barium residue coal ash building block includes, by the mass proportion, 50 cement, 500 mountain sand, 400 barium residue, 100 coal ash, 6 sodium sulfate and appropriate amount of water. According to the invention, the pollution to the environment from barium residue is reduced; clay bricks are replaced with waste materials to achieve waste material utilization, which meets the requirement of developing recycling economy; and the building block cost is lowered. The invention is suitable for building material producing enterprises discharging barium residue.

Description

technical field [0001] The invention relates to a shaped product containing an inorganic binder, in particular to a building block, especially to a production method of a barium slag fly ash block. Background technique [0002] As we all know, clay bricks consume a lot of valuable land resources, so their production and use have been banned. In recent years, industrial waste has begun to enter the field of building materials, and a number of technical solutions have applied for Chinese patents, such as No. 93105763.9 "Using high-calcium fly ash to replace cement to produce wall materials and its production process", No. 98110053.8 "A red mud Sintered wall material", No. 200610164940.X "Energy-saving wall material made of shale and waste residue and its manufacturing method", No. 200710066191.1 "Method for continuously producing environmentally friendly lightweight gypsum wall material by using industrial waste residue", No. 200710038790.2 " Method for preparing lightweight ...
