Abstract
The present invention addresses a technical problem of realizing a sprayable refractory material capable of, even when used in a dry-spraying installation process, ensuring mixability between a silica sol and a refractory composition to promote a hardening reaction, thereby achieving excellent durability. Provided is a dry-sprayable unshaped refractory material which comprises a refractory composition, and a silica sol containing a silica solid component in a concentration of 20 mass % to 50 mass %. The silica sol is added in such a manner that the silica solid component contained in an entirety of the silica sol reaches an amount of 3 mass % to 30 mass % with respect to and in addition to an entirety of the refractory composition assumed as 100 mass %, and the refractory composition contains a Mg- or Ca-containing compound having a particle size of 10 μm or less, wherein a ratio of a content of the Mg- or Ca-containing compound having a particle size of 10 μm or less in the refractory composition to a content of the silica solid component in the entirety of the silica sol is 0.02 or more.
