FROST DAMAGE RESISTANT ADMIXTURE, FROST DAMAGE RESISTANT CONCRETE, AND METHOD OF PRODUCING FROST DAMAGE RESISTANT CONCRETE
To provide an admixture for producing concrete which is excellent in frost damage resistance and is capable of securing fluidity retention, frost damage resistant concrete, and a method of producing frost damage resistant concrete.SOLUTION: The frost damage resistant admixture according to the present invention is a two component type frost damage resistant admixture, consisting of (A) an A agent including solid paraffin, an emulsifier, a foaming agent and a dispersion agent, and (B) a B agent including a nitrite salt and a solvent. Frost damage resistant concrete can be produced by blending the admixture in cement.SELECTED DRAWING: None
【課題】耐凍害性に優れ、かつ流動性保持性が確保されたコンクリートを得るための混和剤、耐凍害性コンクリート、および耐凍害性コンクリートの製造方法の提供。【解決手段】本発明による耐凍害性混和剤は、（Ａ）固形パラフィン、乳化剤、起泡剤、および分散媒を含むＡ剤と、（Ｂ）亜硝酸塩および溶媒を含むＢ剤と、から二液型耐凍害性混和剤である。セメントにその混和剤を配合することで耐凍害性コンクリートを得ることができる。【選択図】なし
