| titleOfInvention | Water-absorbent resin, and soil |
| abstract | Provided is a water-absorbent resin that quickly absorbs water, even in sandbag in which a large amount of the water-absorbent resin has been used, that does not easily form unswollen lump, and that has a high gel swelling volume when water is used to swell the water-absorbent resin. This water-absorbent resin is configured from a polymer of water-soluble ethylenic unsaturated monomers. The physiological-saline absorption capacity of the water-absorbent resin is 40-60 g/g. When a cross-sectional image of the water-absorbent resin is observed by x-ray computed tomography, the fraction of the area of the cross-sectional image that is hollow portions (the hollow area ratio of the cross-sectional image), as calculated on the basis of formula (I), is no more than 10%. (I) Hollow area ratio [%]={total cross-sectional area (B) of hollow portions of the water-absorbent resin/(total cross-sectional area (A) of resin portions of the water-absorbent resin+total cross-sectional area (B) of hollow portions of the water-absorbent resin)}×100%. |
