    摘要: A drying shrinkage-reducing agent which comprises a polymer containing as an essential component at least one structural unit (I) represented by the following formula (1): wherein R1, R2, and R3 independently stand for a hydrogen atom, a methyl group, or a —(CH2)pCOOX group, wherein X stands for a hydrogen atom, a monovalent metal, a divalent metal, an ammonium group, an organic amine group, or a hydrocarbon group, and p is an integer of 0-2; and R4 stands for a hydrocarbon group of 4-30 carbon atoms, and exhibiting surface tension in the range of 25-50 mN/m in a solution containing 0.2 mass % of the polymer in a cement supernatant is provided. The drying shrinkage-reducing agent manifests no dispersibility in an amount capable of attaining necessary drying shrinking-reducing properties and, when used in combination with a dispersing agent, acquires ability to adjust the dispersibility and the drying shrinkage-reducing properties fit for the purpose.

    摘要: Provided is 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 shrinkage-reducing agent for a hydraulic material includes at least one kind of polyoxyalkylene compound (A) as an essential component, in which a concrete or a mortar produced by using the shrinkage-reducing agent for a hydraulic material has a spacing factor of 350 μm or less.
