PURPOSE: Provided is a method for preparing an anti-washout underwater admixture with anti-corrosive function, by which one-part products having both functions as an admixture for underwater concretes and as an anti-corrosive agent are produced. CONSTITUTION: The method for preparing an anti-washout underwater admixture with anti-corrosive function comprises: providing an anti-washout underwater admixture by mixing a cellulose-based thickener with a high-viscosity acrylic thickener; introducing a strength reinforcing agent, a liquid defoamer and a flowing agent into the admixture and compounding them together; and adding a powdery anti-corrosive agent to the compounded product and then mixing. 해양에서 수중 콘크리트 공사시 염화물 이온에 의한 철근의 부식을 방지함과 동시에 수중에서 콘크리트 작업시 시멘트의 씻김 현상을 방지하여 콘크리트의 내구성을 향상시킬 수 있도록 하는 방청기능을 동시에 갖는 수중불분리 방청혼화제의 제조방법이 개시되어 있다. 상기 제조방법은 셀룰로오스계 증점제와 고점도 아크릴계 증점제를 혼합하여 수중 불분리 혼화제를 제조하는 단계; 상기 혼화제에 조강제, 액상소포제 및 유동화제를 투입하여 배합하는 단계; 및 상기 배합물에 분말 방청제를 첨가하여 혼합하는 단계를 포함한다.
