DRY SHRINKAGE-REDUCING AGENT FOR HYDRAULIC MATERIAL-HARDENING BODY, SHRINKAGE-REDUCING METHOD THEREFOR, AND LOW-SHRINKAGE HYDRAULIC MATERIAL-HARDENING BODY
To provide a dry shrinkage-reducing agent for a hydraulic material-hardening body, capable of reducing dry shrinkage in the hydraulic material-hardening body and preventing cracks from occurring due to the dry shrinkage, by applying the agent to the hydraulic material-hardening body; and to provide a shrinkage-reducing method therefor, and a low-shrinkage hydraulic material-hardening body.SOLUTION: This invention relates to a dry shrinkage-reducing agent for a hydraulic material-hardening body, comprising: at least one compound selected from the group comprising a urea derivative and a hydrophilic amine compound; and water. This invention further relates to a shrinkage-reducing method therefor, and a low-shrinkage hydraulic material-hardening body.SELECTED DRAWING: None
【課題】水硬性材料硬化体に適用することで、水硬性材料硬化体の乾燥収縮が低減され、乾燥収縮に起因するひび割れが抑制される水硬性材料硬化体の収縮低減剤、水硬性材料硬化体の収縮低減方法及び低収縮性水硬性材料硬化体を提供する。【解決手段】尿素誘導体及び親水性アミン化合物からなる群より選択される少なくとも１種の化合物と、水と、を含有する水硬性材料硬化体の収縮低減剤、水硬性材料硬化体の収縮低減方法、及び低収縮性水硬性材料硬化体。【選択図】なし
