Document Type: Proceeding Paper

Part of: Foundation Engineering: Current Principles and Practices


The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences are noted between the quick acting agents and those which develop the required expansion forces within 24 hours. Experiences are described whereby such demolition agents were used to fracture rock and other solid materials on projects in the United States, Canada, China and Japan.
