Characteristics of ALC wallboard

ALC partition wall is mainly used for building wall insulation (such as reinforced concrete wall, ceramsite hollow block infilled wall, concrete hollow block wall, clay porous brick wall, etc
), Building roof insulation system, steel roof insulation, ground insulation, cold storage insulation, pavement foundation, etc
During decoration, the light partition board can also be widely used in the internal partitions of offices, commercial and residential buildings, corridors and kitchens
Features of ALC wallboard:
1
Sound insulation
The interior of aerated concrete products is filled with small pores
Thus, it has a good sound insulation effect, and the noise can be reduced by 30-50 dB with different thickness
Due to the porosity of aerated concrete products, when it is not covered by other materials, the sound absorption effect is very good, and the sound insulation effect of 100mm wallboard can reach 40 dB

2
Fire resistance
The thermal conductivity of aerated concrete products is very small, which makes the heat transfer slow, can effectively resist fire, and protect the structure from the impact of fire
It is an inorganic substance and will not burn, and will not produce harmful gas even under high temperature
Therefore, the products are widely used as firewalls and buildings with high fire protection requirements

3
Thermal insulation
The thermal conductivity of aerated concrete products is 0
09-0
18w / M
K
It is 1 / 10 of concrete
It is a building material with excellent thermal insulation performance
In the process of production, many small pores are formed inside
These pores form a static air layer in the material
The thermal insulation of 125 thick plate is equivalent to 370 clay brick wall
It is an ideal building energy-saving material
The heat transfer resistance of grade 05 250 thick block wall is 1
62 (m2
K) / W, The heat transfer coefficient is 0
57w / (m2
K), and the energy saving of a single wall is 65%

4
Light weight
The dry density of aerated concrete products is 400-725kg / m3
It is 1 / 3 of red brick and 1 / 4 of concrete, which can effectively reduce the self weight of buildings and reduce the economic investment of building foundation and structure
The average foundation investment can be reduced by 26
8%, reduce the construction difficulty of soft foundation and improve the construction quality
Therefore, it is known as & ldquo; Concrete floating on the water & rdquo;
