Embodiment Construction

[0015] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0016] Option One

[0017] Chenji fly ash is produced by Guiyang Power Plant in Guizhou, and the cement is ordinary Portland cement (PO42.5). The weight ratio of each raw material is: Chenji fly ash 30~50 parts, cement 10~30 parts , 8-15 parts of phosphogypsum, 10-15 parts of lime, 4-8 parts of silica sand, 0.05-1 part of aluminum powder, and 7-color acrylic rods occupy 10-30% of the area.

[0018] Specific steps are as follows:

[0019] 1) Dry the accumulated fly ash in an oven at 105°C, grind it in a ball mill, and pass it through ...

Abstract

The invention discloses a production method of a nonopaque depositional coal ash autoclaved aerated concrete block. The nonopaque depositional coal ash autoclaved aerated concrete block is prepared from 40-60 parts of depositional coal ash, 10-50 parts of cement, 8-15 parts of ardealite, 10-15 parts of lime, 4-8 parts of silica sand and 0.05-1 part of aluminium powder, and seven-color acrylic barsaccount for 10-70% of an area. The acrylic bars can be arranged in a mode of a letter from A to Z and from a to z or a combination of the multiple letters; the acrylic bars can be monochromatic (redor orange or yellow or green or blue or indigo or purple) or multicolor, and the developed nonopaque depositional coal ash autoclaved aerated concrete block meets the requirements of an A3.5 grade. According to the production method of the nonopaque depositional coal ash autoclaved aerated concrete block, 30 to 65% of the depositional coal ash and the waste acrylic bars are adopted, the pollutionaction of the depositional coal ash and the waste acrylic bars is reduced, meanwhile, the type of blocks is broadened, and the nonopaque depositional coal ash autoclaved aerated concrete block can beused for a high-rise frame infilled wall, and has very larger social, economic and environment-friendly benefits.

Description

technical field [0001] The invention relates to a method for making a light-transmitting aged fly ash autoclaved aerated concrete block, which belongs to the technical field of inorganic non-metallic materials. Background technique [0002] As a traditional solid waste, fly ash has achieved remarkable results under the guidance of national policies in the past two years. The supply of fly ash newly produced by major power plants is currently in short supply, leading to continuous rise in the price of fly ash , has brought difficulties in raw material supply and greater cost pressure to aerated concrete enterprises that use fly ash as one of the main raw materials. On the other hand, before the resource utilization of fly ash has achieved results, the conventional treatment method of fly ash is centralized stockpiling. After decades, each power plant has been equipped with several storage yards. Due to the accumulation of fine coal The ash activity is low, and most of it has...
