The present invention relates to a concrete admixture and a method for manufacturing the same. The concrete admixture according to an embodiment of the present invention is a concrete admixture added to mortar concrete, gravel concrete, or red clay mortar and preventing cracking during the plastering of the walls and floors of various buildings. The concrete admixture is produced by the dilution in water of a sodium salt aqueous solution to which salt, oxide, or hydroxide containing alkaline earth metal has been added after selection, the dilution being performed to satisfy 0.05 to 1.00% on a volume basis. According to the concrete admixture of the present invention and according to a flooring material, the addition to the mortar concrete, gravel concrete, or red clay mortar can result in the prevention of the cracking during the plastering of the walls and floors of the various buildings. 콘크리트 혼화제 및 그 제조방법이 개시된다. 본 발명의 실시예에 따른 콘크리트 혼화제는: 몰탈 콘크리트, 자갈 콘크리트 또는 황토몰탈에 첨가되어 여러 가지 건축물의 벽, 바닥의 미장시 균열을 방지하는 콘크리트 혼화제로서, 알카리토금속을 함유하는 염, 산화물 및 수산화물 중 하나를 선택하여 첨가된 나트륨염 수용액을 물에 부피기준 0.05 내지 1.00 %로 희석하여 제조된 것을 특징으로 한다. 본 발명에 따른 콘크리트 혼화제에 따르면, 바닥재에 따르면, 몰탈 콘크리트, 자갈 콘크리트 또는 황토몰탈에 첨가되어 여러 가지 건축물의 벽, 바닥의 미장시 균열을 방지할 수 있다.
