SHRINKAGE REDUCING AGENT FOR HYDRAULIC MATERIAL |
摘要 |
Provide is a hydraulic material composition, including cement and a shrinkage-reducing agent for a hydraulic material, which does not require a combination with any other admixture, is inexpensive, and is capable of suppressing a reduction in strength of a hardened concrete material, suppressing generation of a crack in a hardened concrete material by virtue of its excellent shrinkage-reducing ability, and imparting excellent freeze-thaw resistance. The hydraulic material composition includes cement and a shrinkage-reducing agent for a hydraulic material including at least one kind of polyoxyalkylene compound (A) as an essential component, and has a spacing factor of 350 µm or less. |
