PURPOSE: Carbon dioxide absorbent using recycled waste materials and concrete including the same are provided to be cost effectively prepared by mixing an industrial byproduct with an additive selected from a group including minerals, cement, and the combination of the same. CONSTITUTION: Carbon dioxide absorbent using recycled waste materials includes tailing or an industrial byproduct and an additive. The surface of the tailing or industrial byproduct is reformed based on a basic solution. The additive is selected from a group including minerals, cement, and the combination of the same. The weight ratio of the tailing or the industrial byproduct and the additive is 9:1 to 6:4. The tailing or the industrial byproduct is fly ash, waste tire, blast furnace slag, collected dust, or the combination of the same. [Reference numerals] (AA) Fly ash/Ca(OH)_2 + cement (example 1); (BB) Fly ash/Ca(OH)_2 + LDH (example 2); (CC) Fly ash + cement (comparative example); (DD) Time(min)
