Abstract
The invention provides an oil shale residue aerated brick. The oil shale residue aerated brick is prepared from the following raw materials: 20 to 30 weight parts of oil shale residue, 25 to 30 weight parts of coal ash, 5 to 10 weight parts of cement, 4 to 6 weight parts of modified attapulgite, 5 to 10 weight parts of mica powder, 5 to 10 weight parts of ceramics factory waste, 5 to 10 weight parts of calcium carbonate powder, 10 to 15 weight parts of lime, 0.1 to 0.3 weight percent of triethanolamine lime, 4 to 5 weight parts of gypsum, 0.02 to 0.08 weight part of aluminum powder, nekal which is 3 to 5 percent based on weight of aluminum powder, 0.01 to 0.02 weight part of calcium bicarbonate, 2 to 3 weight parts of volcanic rock, 1 to 2 weight parts of lignocellulose, 0.3 to 0.5 weight part of soda ash, 0.03 to 0.05 weight part of borax, 1 to 2 weight parts of sodium diacetate, 1 to 2 weight parts of hydroxypropyl methyl cellulose sodium, and 1 to 2 weight parts of superfine polyvinyl alcohol. The oil shale residues are added into the raw materials of the aerated brick, other conventional aids and modified nano aids are added, and the aerated brick which is processed by an appropriate process is low in cost and high in performance, achieves the cyclic economy effect of changing waste into wealth, and reduces pollution; and the processed aerated brick has the characteristics of light volume weight, high thermal insulation property, good sound absorption effect, and high intensity and can be used for a non-load bearing wall body or a load-bearing wall body.
Description
technical field [0001] The invention relates to the field of building materials, in particular to an oil shale slag aerated brick and a preparation method thereof. Background technique [0002] The aerated concrete block is a solid block made of cement, slag, sand, lime, etc., added with an air-generating agent, stirred and formed, and autoclaved. According to the application, the aerated concrete can be divided into non-load-bearing blocks , load-bearing blocks, insulation blocks, wall panels and roof panels five. [0003] Aerated brick has the advantages of light bulk density, high thermal insulation performance, good sound absorption effect, certain strength and machinability, etc. It is one of the earliest and most widely used lightweight wall materials in China. [0004] Under the background of the increasingly important protection of energy and natural resources in the world, with the adjustment of industrial policies and the improvement of environmental protection aw...
