Now our country is vigorously promoting prefabricated buildings, and prefabricated buildings have great development opportunities. As a new wall material, autoclaved aerated concrete panel is more and more popular because of its unique advantages. But what are the characteristics or advantages of autoclaved aerated concrete panel that are so popular among people?
Ⅰ.What is autoclaved aerated concrete board
Autoclavate aerated concrete board (ALC board) is a new kind of light and porous green building material with cement, lime and silica sand as the main raw materials and different quantities of anti-corrosion steel mesh added according to the structural requirements.After high temperature and high pressure, steam curing, the autoclaved aerated concrete panel with porous crystal is produced by reaction. Its density is smaller than that of ordinary cement materials, and it has excellent fire-resistant, fireproof, soundproof, heat insulation, heat preservation and other unparalleled performance.
Ⅱ.The characteristics and advantages of autoclaved aerated concrete panel
1.Light weight: specific gravity is only 500~650kg/m3, only 1/4 of concrete, 1/3 of clay brick, known as floating on the surface of the concrete.The design value is 650kg/m3.
2.Fire resistance: 100mm thick panel can reach 3.82 hours, 125mm thick panel can reach more than 4 hours, is a first-class fire material.
3. Insulation: the thermal conductivity is 0.114, and the insulation effect of the 125mm thickness material can reach the ordinary 370mm thick brick wall.Is a single material can achieve building energy saving more than 65% of the new building materials.
4.Sound insulation: The sound insulation index of 100mm thick panel (two-sided putty) reaches 40.8dB (through loss);The acoustic insulation index of 120mm thick panel (two-sided putty) reaches 45dB (through loss);Sound insulation index of 150mm thick panel (double-sided putty) is 48dB (through loss);There are many small pores inside the ALC panel, which have the dual performance of sound insulation and sound absorption.
5.Earthquake resistance: it can adapt to large interlaminar Angle displacement, allowing 1/150 of the interlaminar Angle to reach 1/120 when special contact is adopted, and no panel shedding will occur at 1/20 of the interlaminar Angle at all contacts.
6. Environmental protection: Non-radioactive, with an hourly exposure of 12 /h, equivalent to the level on outdoor grassland;ALC is a new type of environmentally friendly building materials, which can save energy consumption in the process of use. It belongs to the national key building materials and enjoys duty-free access.
7.Bearing capacity: The panels are equipped with double-layer and two-way steel mesh inside, respectively providing external wall panels, partition wall panel, roof panel, floor panel, decorative panel and so on.
8. Crack resistance: THE ALC panel is reinforced by the steel bar after rust treatment, through high temperature, high pressure, steam curing, in the inorganic material shrinkage ratio is minimum, with a special polymer binder caulking, effectively prevent cracking.
9. Convenience: THE ALC panel is processed by the fixed length after the actual measurement on site, which is the precast product of the factory, with high precision, planing, sawing and drilling.Adopt dry operation, installation is simple, the craft is simple, cancels the traditional wall construction column, the waist beam, the plastering, the direct batch scraping putty child, greatly shortens the construction period, improves the efficiency and the construction quality.
10.Economy: using ALC board as wall materials, can effectively improve the structure of the usable floor area, reduce the energy consumption and meet the national building energy efficiency standards, as required by the same sound insulation, fire prevention, ALC minimum panel thickness, and don’t post, ring beam, beam waist auxiliary components, such as this can reduce wall load, thus reducing construction cost.
11. Creativity: THE ALC board can be made into artistic decorative panels. After the material is installed, it can directly achieve the effects of brick, lattice, horizontal grain, imitation brick, imitation stone and so on.
12. Extensibility: it can be used for the internal and external walls, floor boards, roof boards, firewalls, explosion-proof walls, steel structure beams and columns fire maintenance, sound insulation walls, old buildings and storey modification, etc.
13. Diversity: another 50mm thin panel and 30mm super thin panel (can be used as external wall insulation board and fireproof board).
14. Quickness: It eliminates the mixing, laying, plastering, reinforcement, formwork, concrete and other types of work in the traditional block technology. Only the panel installers can finish all the work, avoiding the conflict and mutual restriction of the types of work.
15. Uniqueness: The width of ALC panel is 600mm and the maximum length can be 6 meters (150mm thick), while the length of other panels cannot reach 6 meters.
