A Composite of light weight foamed concrete with multi function and manufacturing method thereof
The present invention relates to high-strength lightweight foamed concrete, which is used at a floor of apartment buildings to reduce impact noise between households of upper and lower floors and display a high thermal insulation performance, and has a smooth filling performance in an underground cavern region or an abandoned cavern of an exhausted mine. The present invention relates to a multifunctional composition of lightweight foamed concrete and a manufacturing method thereof, in which fibrous materials are combined, so that cracks which are easy to occur in the lightweight foamed concrete are reduced. In addition, a foamed EVA chip, waste urethane foam or an inorganic lightweight aggregate having an effect of reducing the impact noise between households of the upper and lower floors in the apartment building by a porous cellular structure is used in the lightweight foamed concrete according to the present invention. Moreover, a modified foaming agent is used, in which the modified foaming agent is mixed with a foam stabilizer for preventing foam from being dissipated by improving porosity of the foam due to use of an inorganic foaming material and improving stability of foam generated from a known foaming agent. Accordingly, the performances of the impact noise reduction and the thermal insulation performance applied between upper and lower floors in a building are improved, and the composition is used for filling the abandoned cavern of the exhausted mine or an underground structure. The multifunctional composition of the lightweight foamed concrete includes: 0.55 to 0.75 vol% of bubble foam produced by the modified foaming agent; and 0.25 to 0.45 vol% of a composition produced by mixing cement with a lightweight aggregate mixture.
