A high insulation and high stiffness lightweight concrete composite and a floor structure for interlayer impact sound reduction using a high insulation and high stiffness lightweight concrete composite are provided to cut off the transfer of floor impact sound from the upper floor to the lower floor in a multistoried building effectively. A high insulation and high stiffness lightweight concrete composite is placed on the upper part of a concrete slab structure to reduce impact sound transferred from the upper floor, and composed of 47.4~70.2 weight percent perlite, 5.3~10.6 weight percent plaster, 5.3~10.6 weight percent calcium hydroxide, 10.6~21.2 weight percent calcium carbonate and 2.6~5.3 weight percent calcium chloride per 100 weight percent cement. A floor structure for interlayer impact sound reduction using a high insulation and high stiffness lightweight concrete composite comprises a concrete slab layer(10) dividing the upper floor and the lower floor of a building, a high insulation and high stiffness lightweight concrete layer(20) formed by placing a concrete composite on the upper part of the concrete slab layer, a cement mortar layer(30) formed on the upper part of the high insulation and high stiffness lightweight concrete layer, and a finishing layer(40) formed on the upper part of the cement mortar layer. |
