Composition for foam concrete with high insulation for reducing of floor impact sound manufacturing method of foam concrete using the same and foam concrete with high insulation for reducing of floor impact sound manufactured using the same

摘要

The foamed concrete composition for reducing floor impact sound of the present invention comprises bubbles, water, cement and fly ash, wherein the bubbles are contained in an amount of 40 to 60% by volume based on the total volume of the foamed concrete composition, and the compounding ratio W / B) is 0.40 to 0.55:[Equation 1]Compounding ratio (W / B) = water unit weight / solid content end unit weight(Wherein, in the formula 1, the water unit weight is the weight (kg) of water per unit m 3 contained in the composition, and the solid end unit weight is the total weight (kg) at the end of the solid content per unit m 3 contained in the foamed concrete composition ).
