Due to the inside of the foam concrete pore structure, sound-absorbing effect is quite perfect. So the foam concrete can reduce noise pollution and improve living conditions.
In 2009, foam concrete insulation board used in Chinese high speed railway. When the train fast moving, it can lead to high pressure and high frequency noise, metal and produce a sonic boom will accordingly. In order to avoid damage to buildings and residents along the rail, sound insulation should be based on both sides of the railway. The committee is made up of inorganic foam concrete, by the open cell foam layer low density and high density closed cell foam layer, at the same time, it has the advantages of other fir resistance, heat insulation, sound absorption, sound insulation, high compressive strength, and so on.
We GD2000 foam concrete mixer is controlled by PLC, can make the different density of foam concrete, can satisfy different applications. Our products may be a good choice for you.
