AI Technical Summary

Problems solved by technology

However, the melting and solidification technology has not been used in China due to the high processing cost.
In short, at present, the processing cost of fly ash is relatively high, the total amount of fly ash to be processed is small, and it is impossible to consume fly ash on a large scale and cannot meet the processing demand of my country's growing fly ash production. It is necessary to find a new comprehensive disposal of fly ash Direction of development

Abstract

The invention relates to the field of novel building materials, in particular to a microbial fly ash building material and a preparation method thereof; it is made from the following raw materials in parts by weight: 50-70 parts of waste incineration fly ash, 2-10 parts of silicon micropowder, and pulverized coal. 20-30 parts of ash, 3-5 parts of cement, 10-15 parts of slaked lime, 5-8 parts of red mud, 7-9 parts of steel slag powder, 0-30 parts of 50-80 mesh pearlescent sand, 10-40 parts of bacterial liquid, 0-20 parts of nutrient solution, 2-4 parts of pure acrylic emulsion, 0.5-1 part of potassium silicate, 0.05-0.2 part of polyacrylamide, 0.1-0.5 part of KH570 silane coupling agent; A kind of microbial fly ash building materials, including fly ash ceramsite, fly ash concrete, fly ash permeable bricks and fly ash curbs, the preparation method is green and pollution-free, the solid waste utilization rate is high, it has good environmental benefits, and has a good practical Value.

Description

Technical field [0001] The invention involves the field of new building materials, and specifically involves a microbial flying ash building materials and their preparation methods. Background technique [0002] Flying ash generally refers to any solid particles in the flue gas generated by fuel combustion. It usually includes the chimney of the armal power plant and the flue fly ash and the waste incineration. [0003] The waste -incineration fly ash (MSWI Fly ASH) is a product of domestic waste incineration, which accounts for 3 to 5 % of the waste incineration, because it contains a variety of organic poisons such as heavy metals and dual villain and has a large immersion toxicity. It was included in the "National Dangerous Waste List" (code 772-002-18). The "Control Standard for Pollution Control in Lomason Fitting Field" (GB 16889-2008) stipulates that the waste incineration fly ash through the solidification / stable treatment can be entered into the sanitary landfill for lan...
