Embodiment 1

[0023] The composition of the ceramsite concrete slab is as follows: sulfoaluminate 425# cement 380kg, stone powder 850kg, ceramsite 173kg, water 115kg and two layers of barbed wire. Among them, the diameter of ceramsite is 5~20mm. Stir the sulfoaluminate 425# cement, stone powder, ceramsite and water evenly to obtain a mixture, and put a part of the evenly stirred mixture into the mold first. Then place a layer of barbed wire in the mold. Then, after putting the evenly stirred mixture into the mold, lay a layer of barbed wire, and enter the vibrating process. The size of the barbed wire is 795mm×795mm. The barbed wire has a diameter of 0.7mm and a grid size of 15mm×15mm. The galvanized wire mesh mainly plays the role of enhancing the elasticity of the ceramsite concrete slab.

[0024] The size of the ceramsite concrete slab prepared after form removal and curing is 800mm×800mm. The thickness of the ceramsite concrete slab is only 25mm, which is very convenient for transp...

Embodiment 2

[0027] The composition of the ceramsite concrete slab is as follows: sulfoaluminate 425# cement 385kg, mineral sand 790kg, ceramsite 175kg, water 115kg and two layers of barbed wire. Among them, the diameter of ceramsite is 5~10mm. Mix sulfoaluminate 425# cement, ore sand, ceramsite and water evenly to obtain a mixture, and put a part of the evenly stirred mixture into the mold first. Then place a layer of barbed wire in the mold. Then, after putting the evenly stirred mixture into the mold, lay a layer of barbed wire, and enter the vibrating process. The size of the wire mesh is 880mm×580mm. The barbed wire has a diameter of 0.72mm and a grid size of 19mm×19mm. The galvanized wire mesh mainly plays the role of enhancing the elasticity of the ceramsite concrete slab.

[0028] The size of the ceramsite concrete slab prepared after form removal and curing is 900mm×600mm. The thickness of the ceramsite concrete slab is only 25mm, which is very convenient for transportation a...

Embodiment 3

[0031] The composition of the ceramsite concrete slab is as follows: ordinary silicate 425# cement 396kg, fly ash 900kg, ceramsite 179kg, water 117kg and two layers of steel wire mesh. Among them, the diameter of ceramsite is 5~15mm. Mix ordinary silicate 425# cement, fly ash, ceramsite and water to obtain a mixture, and put a part of the mixture in the mold first. Then place a layer of steel mesh in the mold. Then, after putting the evenly stirred mixture into the mould, lay a layer of steel wire mesh and enter the vibrating process. The size of the wire mesh is 880mm×880mm. The steel wire mesh has a diameter of 0.83mm and a grid size of 23mm×23mm. The galvanized steel wire mesh mainly plays the role of enhancing the elasticity of the ceramsite concrete slab.

[0032] The size of the ceramsite concrete slab prepared after form removal and curing is 900mm×900mm. The thickness of the ceramsite concrete slab is only 25mm, which is very convenient for transportation and inst...

Abstract

The invention discloses a ceramsite concrete slab. The ceramsite concrete slab per cubic meter mainly comprises the following raw materials: 380-410kg of cement, 790-900kg,coal ash or furnace clinker, 173-180kg of ceramsite, 115-120kg of water and a wire mesh. The ceramsite concrete slab provided by the invention has high strength, freezing resistance and anti-swelling efficiency and can be used as an outer wall of a building; the ceramsite concrete slab can be made into a small size so as to meet the break joint requirement during installation, is suitable for strength during installation and rigidity requirement of the wall space and has wide applicable range; the ceramsite concrete slab achieves the anti-seismic effect in the structure, has low density, is light in mass, and has convenience in transportation and field cutting installation; and the ceramsite concrete slab has good heat preservation effect and sound insulation effect and can realize the self heat preservation function.

Description

technical field [0001] The invention relates to a building material, in particular to a ceramsite concrete slab. Background technique [0002] Ceramsite board is a kind of building board made of ceramsite as the main raw material. Compared with other lightweight concrete panels, ceramsite panels have the advantages of high strength, light weight, low cost, no combustion, and a wide range of applications. Therefore, ceramsite panels have been widely used in the construction industry to replace ordinary bricks. However, the current market is dominated by large-sized ceramsite panels or bricks, while small-area ceramsite panels have a wider range of application than large-size ceramsite panels, which reflects its value. Especially in terms of shock resistance, it has an incomparable effect. In addition, the current ceramsite board is only used as a building material for non-load-bearing internal and external partition walls due to its insufficient strength. Contents of the ...
