Yttrium-element autoclaved aerated concrete block and preparation method thereof

Abstract

The invention discloses an yttrium-element autoclaved aerated concrete block and a preparation method thereof. The yttrium-element autoclaved aerated concrete block is divided into an yttrium-element sand aerated concrete block and an yttrium-element ash aerated concrete block and belongs to the field of building materials. The yttrium-element sand aerated concrete block is composed of the following raw materials by weight parts: 55-70 parts of sand, 0.03-0.06 parts of yttrium oxide, 23-28 parts of lime, 6-11 parts of cement, 2-6 parts of gypsum, 0.8-1.2 parts of aluminum powder and 2-7 partsof calcium-based bentonite. The yttrium-element ash aerated concrete block is composed of the following raw materials by weight parts: 60-70 parts of coal ash, 0.03-0.06 parts of yttrium oxide, 25-30parts of lime, 6-8 parts of cement, 2-6 parts of gypsum, 0.8-1.2 parts of aluminum powder and 2-7 parts of calcium-based bentonite. Compared with the present autoclaved aerated concrete block, the yttrium-element autoclaved aerated concrete block has the advantages that the filling property is greatly promoted, namely, the compression strength is promoted.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a yttrium element autoclaved aerated concrete block and a preparation method thereof. Background technique [0002] According to the existing definition standards for new wall materials, buildings such as concrete shear wall structures, frame structures, and frame-shear structures are all listed as new wall material buildings. The existing concrete is composed of main raw materials such as cement, sand, and stone. , cement as a cementitious material consumes a large amount of non-renewable resources such as limestone and clay and a large amount of high-quality energy such as coal in the production process; in the production of concrete, a large amount of limestone is added, and the limestone resources consumed by the two The economic value is far greater than the economic value of the clay resources used to burn bricks; moreover, the walls and frames are basically s...

[0002] According to the existing definition standards for new wall materials, buildings such as concrete shear wall structures, frame structures, and frame-shear structures are all listed as new wall material buildings. The existing concrete is composed of cement, sand, stone and other main raw materials. , cement as a cementitious material consumes a large amount of non-renewable resources such as limestone and clay and a large amount of high-quality energy such as coal in the production process; in the production of concrete, a large amount of limestone is added, and the limestone resources consumed by the two The economic value is far greater than the economic value of the clay resources used to burn bricks; moreover, the walls and frames are basically solid, and the concrete has a large specificity and a large amount, which not only wastes raw materials, but also increases the load of the building and increases the Basic treatment and construction costs, and the production cycle is long, and the sound insulation and heat resistance are not good; although the existing autoclaved aerated concrete overcomes the above shortcomings, its viscosity is high, and the materials are not easy to mix evenly
