Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A shrinkage-reducing agent for a hydraulic material, comprising at least one kind of polyoxyalkylene compound (A), which is a compound selected from the group consisting of (i) polyalkyleneglycols, (ii) oxyethylene adducts of lower alcohols and higher alcohols each having 8 or more carbon atoms, and (iii) adducts of two or more kinds of oxyalkylenes essentially including an oxyethylene of lower alcohols and higher alcohols each having 8 or more carbon a…
