摘要： The invention provides a cement admixture that improves the ability of concrete to bring about high initial strength, works in favor of enhancing the effect on hexavalent chromium reductions, and is less likely to decrease in the effect on hexavalent chromium reductions even upon storage as well as a method for reducing hexavalent chromium. The invention is embodied as (1) A cement admixture, characterized by comprising an expanding material containing free lime, a hydraulic compound and calcium sulfate anhydrite, and a tin sulfate-containing substance; (2) The cement admixture according to (1), characterized in that the tin sulfate-containing substance is contained in an amount of 0.2 to 8 parts by mass—as calculated on a tin sulfate basis—in a total of 100 parts by mass of the expanding material and the tin sulfate-containing substance; (3) The cement admixture according to (1) or (2), characterized in that the expanding material has been treated with carbon dioxide gas to form calcium carbonate therein; (4) The cement admixture according to any one of (1) to (3), characterized in that the expanding material has been surface treated with a shrinkage reducer; (5) A cement composition, characterized by containing cement, and the cement admixture according to any one of (1) to (4); and (6) A method for reducing hexavalent chromium, characterized by use of the cement composition according to (5).
摘要翻译：本发明提供了一种提高混凝土产生高初始强度的能力的水泥混合物，有利于增加对六价铬还原的影响，并且即使在储存时也不太可能降低对六价铬还原的影响，一种降低六价铬的方法。本发明体现为：（1）一种水泥混合物，其特征在于包含含有游离石灰的膨胀材料，水硬性化合物和无水硫酸钙，以及含硫酸锡物质; （2）根据（1）所述的水泥混合物，其特征在于，所述含硫酸锡物质的含量为0.2〜8质量份（以硫酸锡为基准），总计为100质量份的膨胀材料和含硫酸锡物质; （3）根据（1）或（2）所述的水泥外加剂，其特征在于，所述膨胀材料已经用二氧化碳气体处理以在其中形成碳酸钙; （4）如（1）〜（3）中任一项所述的水泥外加剂，其特征在于，所述膨胀材料用减缩剂进行表面处理; （5）一种水泥组合物，其特征在于含有水泥，和（1）〜（4）中任一项所述的水泥混合物; （6）一种减少六价铬的方法，其特征在于使用（5）所述的水泥组合物。
