Abstract: PURPOSE: A chemical compound forming method is provided to form substances having a semi-stable form more easily and stably as a product is formed with a mechanical alloy method by grinding a reactant into pieces of 50nm or less. CONSTITUTION: A chemical compound forming method comprises; a step for preparing a reactant which includes at least three elements; and a step for forming a product with a mechanical alloy method by grinding a reactant into pieces of 50nm or less. The step for preparing a reactant comprises; a step for primarily grinding an initial reactant with a ball mill method; and a step for secondarily grinding the ground initial reactant with a planetary ball mill process. [Reference numerals] (AA) Intensity(cds); (BB) Scattering angle(°)

Abstract: PURPOSE: An improved floor structure for reducing impact noise from the floor is provided to effectively reduce heavy impact noise by dispersing impact through a buffer material and a connecting material. CONSTITUTION: An improved floor structure for reducing impact noise from the floor comprises a slab(S), a buffer material(B), finishing mortar(F), a connector(SS), and aerated concrete(A). The slab is located on the bottom of a floor structure. The buffer material lies on the top of the slab. The finishing mortar is formed on the top of the buffer material. The lower end of the connector is fixed in the slab and the upper end of the connector is installed in the finishing mortar. The aerated concrete is formed between the buffer material and the finishing mortar.
