| titleOfInvention | Cement admixture, cement composition, and hexavalent chromium reduction method using same |
| abstract | Provided are a cement admixture and a hexavalent chromium reduction method yielding superior initial concrete strength, having high hexavalent chromium reduction effects, and exhibiting little decrease in hexavalent chromium reduction effects even when stored as a cement admixture. (1) A cement admixture including a tin sulfate-containing substance and an expansive material containing free lime, a hydraulic compound, and anhydrite; (2) the cement admixture of (1), wherein the amount of the tin sulfate-containing substance is 0.2 to 8 parts by mass in terms of tin sulfate per total 100 parts by mass expansive admixture and tin sulfate-containing substance; (3) the cement admixture of (1) or (2), wherein the expansive admixture is treated with carbon dioxide gas to generate calcium carbonate; (4) the cement admixture of any of (1) to (3), wherein the expansive admixture is surface-treated using a shrinkage reducing agent; (5) a cement composition containing the cement admixture of any of (1) to (4); and (6) a hexavalent chromium reduction method using the cement composition of (5). |
