Abstract

The invention provides a chromic slag aerated brick. The chromic slag aerated brick is prepared from the following raw materials: 20 to 30 weight parts of chromic slag, 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 barium carbonate slag, 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, oxyparaffin soap which is 3 to 5 percent based on the weight of the 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 sodium silicate, 0.03 to 0.05 weight part of borax, 1 to 2 weight parts of sodium hexametaphosphate, 1 to 2 weight parts of hydroxypropyl methyl cellulose sodium and 1 to 2 weight parts of superfine polyvinyl alcohol. Chromic slag is added into the raw materials of the aerated brick, other conventional aids and modified nano aids are added, and the aerated brick 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 performance, good sound insulation 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 a chromium 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 my country. [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...
