Processing: aerated concrete has good processing performance. You can saw, to dig, to nail, to mill, to drill. And can be added to steel in the manufacturing process. To the construction of a great convenience and flexibility. Noise: from aerated concrete pore structure shows that, due to the internal structure of aerated concrete, like bread, light brick, evenly distributed a large number of closed pores, light brick, it has generally do not have the sound-absorbing materials performance. 1, light weight, reduce the building load: dry density 300-1200kg / m3 ;, 1 / 5-1 / 8.2, insulation, heat insulation, sound insulation and excellent performance of ordinary concrete: its thermal conductivity 0.08-0.16w / mk, 24cm wall insulation amount to 60dB, to meet the building's exterior, household wall insulation, sound insulation requirements. 3, good compression performance: compressive strength greater than 0.5Mpa, maximum strength up 10.5Mpa more.
