MONOLITHIC REFRACTORY FOR DRY BLOWING

摘要

The invention makes it possible to ensure mixing of a silica sol and a refractory material and to accelerate a curing reaction when a dry-blowing construction method is used, and consequently achieves a refractory for blowing of excellent durability. This monolithic refractory for dry blowing includes a refractory material, and a silica sol having a concentration of solid silica at 20-50 mass%. The silica sol is added so that the solid silica included in the total quantity of silica sol reaches 3-30 mass% relative to the total 100 mass% of the refractory material. The refractory material contains a compound including Mg or Ca at a particle size of 10 mum or smaller. The amount of the compound including Mg or Ca at a particle size of 10 mum or smaller contained in the refractory material is 0.02 or more with respect to the amount of solid silica contained in the total quantity of silica sol.
