ABSTRACT:
A demolition agent for brittle materials in the form of a powder mixture comprising 100 parts by weight of quicklime, 0.05 to 5 parts by weight of a carbonate and either or both of 0.01 to 5 parts by weight of a hydroxy-carboxylic acid or its salt and 0.1 to 5 parts by weight of a fluidization agent. This demolition agent is used by admixing with water to obtain an aqueous slurry, pouring the slurry into a hole drilled in a brittle material and allowing it to stand to demolish the brittle material by means of expansive pressure from the slurry.
