Porosity is the construction standard for foam concrete buildings

Porosity is the construction feature of foam concrete buildings. Its advantages include the following:
1) Light material. For foamed concrete, due to the "porous" nature of foamed concrete, there are voids in this material, coupled with the low density of foamed tissue itself, which reduces the weight of the entire foamed concrete. According to the statistics of foam concrete construction experts, foam concrete materials have a weight reduction of 50% -70% compared with traditional concrete materials.
2) Strong performance. The high performance of this new type of foamed concrete material is mainly manifested in two aspects, namely heat insulation and heat preservation. There are pores of various sizes in the foam concrete, which can form a heat insulation layer inside. Affected by the density grade and thermal conductivity, the role of foam concrete in thermal insulation is also particularly significant.
3) Fire resistance. In essence, foam concrete is an inorganic material. This material has the characteristics of "fire resistance" and excellent fire resistance. It belongs to Class A fireproof material. In addition, the use of this new foam concrete material in the building is also a good "sound insulation layer" to reduce the volume of external noise.
 4) Go green. The active use of new materials by foam concrete manufacturers can not only meet the requirements of building construction standards, but also play a good role in environmental protection. Selecting foam concrete materials instead of traditional materials can save resource consumption and reduce waste of construction resources.
 5) Thermal Conductivity. The main characteristic feature of foam concrete is its low thermal conductivity, which gives it better insulation properties. This is due to the great number of closed cavities that form the multi–cellular structure and results in a 50mm layer of foam concrete, with a density of 400kg/m3, having approximately the same excellent heat insulation value as a 25mm thickness of cork.
Low water absorption. The solid matrix of cementitious slurry surrounding the fine cell structure of the foam concrete greatly reduces the capillary action of moisture
