Manufacturing technology of lightweight aerated concrete using expandable lightweight aggregate
The present invention relates to a technology of producing lightweight aerated concrete using expandable lightweight aggregate. The present invention provides a technology of producing lightweight non-combustible sandwich panels using expandable lightweight aggregate and lightweight cellular concrete to ensure non-combustible performance and no toxic gas emission in case of fire. According to the present invention, the lightweight aerated concrete is produced by mixing, at a combination ratio, about 20 to 30 parts by weight of cement; about 20 to 40 parts by weight of foam with a density of 40 to 50 kg/cm^2 produced at air pressure of about 8 to 10 kg/cm^2 after diluting a surfactant mainly including as a main component lauryl alkyl ether sulfonate with water at a ratio of 40 : 1; and about 40 to 50 parts by weight of pearlite or expanded vermiculite, which is foaming lightweight aggregate having continuous pores. The lightweight aerated concrete of the present invention can be used for sandwich panels, which are insulation and soundproofing inner and outer wall finishing materials of building structures.
