preparation example Construction

[0031] Another object of the present invention is to provide a method for preparing the high-performance air-entraining block, which is characterized in that it includes the following steps: after mixing the components uniformly according to parts by weight, to obtain a mixture, and then adding mass The water is 8-12 times the mass of the mixture, stir evenly to obtain slurry, control the pouring temperature at 35-50°C, and then pour it into the mold through the pouring machine, and carry out a period of 2-4H under the environment of 40-65°C Then, the aerated body is cut by a cutting machine to produce a semi-finished aerated block of the required size and specification; then the semi-finished aerated block is grouped and sent to the curing room for waiting Autoclave curing; finally put the semi-finished aerated block cured to a certain hardness into the autoclave and use 1.1-1.8MPa water vapor to boost the pressure for 1-3 hours, keep the pressure for 5-12 hours, and depressur...

Embodiment 1

[0036] Embodiment 1 provides a high-performance aerated block, which is characterized in that it includes the following components in parts by weight: 15 parts of lime, 15 parts of cement, 60 parts of tailings powder, 2 parts of gypsum, 0.5 part of aluminum powder, plus 0.03 parts.

[0037] The tailings powder is copper tailings powder; the particle size of the tailings powder is 0.3 mm.

[0038] The cement is ordinary Portland cement.

[0039]The high-performance aerated block also includes 2 parts of solid waste; the solid waste is composed of the following raw materials in parts by weight: 1 part of coal gangue, 2 parts of slag, and 2 parts of mining waste rock.

[0040] The high-performance air-filling block also includes 0.5 part of soluble β-cyclodextrin polymer.

[0041] The admixture includes the following components in parts by weight: 2 parts of rosin-based hyperbranched epoxy resin, 4 parts of pozzolan, 0.5 part of carbon fiber, and 0.3 part of λ-carrageenan.

Abstract

The invention discloses a high-performance aerated block which is characterized by comprising the following components in parts by weight: 15-20 parts of lime, 15-20 parts of cement, 60-65 parts of tailing powder, 2-3 parts of gypsum, 0.5-0.6 part of aluminum powder and 0.03-0.05 part of additive. The additive is prepared from the following components in parts by weight: 2-5 parts of rosin-based hyperbranched epoxy resin, 4-8 parts of volcanic ash, 0.5-1.5 parts of carbon fiber and 0.3-0.6 part of lambda carrageenan. The invention further provides a preparation method of the high-performance aerated block. The high-performance aerated block disclosed by the invention is excellent in comprehensive performance, more excellent in mechanical property, higher in performance stability and waterseepage prevention performance, lower in drying shrinkage value and safer and more environment-friendly to use.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a high-performance aerated block and a preparation method thereof. Background technique [0002] Aerated blocks are aerated concrete blocks produced by high-temperature autoclaved equipment. They can be tailored according to different local raw materials and conditions. The raw materials can be river sand, fly ash, ore, etc. Utilization is beneficial to environmental protection and truly turns waste into treasure. The aerated block has light bulk density, heat preservation, heat insulation, sound insulation, and is easy to process. It is made of a variety of mixtures, rich in raw materials, and has good social and economic benefits. It is an ideal wall material to replace traditional solid clay bricks. [0003] At present, the internal air holes of the aerated block are connected, which affects the thermal insulation performance, and there are also shortco...
