The existing rock blasting & expansive demolition agents methods that applied to small and midium sizes of rocks & concrete demolition have caused diverse problems such as dirty scattering, noise, tremor, public complaints, environment destruction, waste treatment, and so this researcher examined the possibility of rock demolition by using the expansibility of dried woods which are environment friendly and high in recycling rate and economical to solve such problems. Maximum swelling pressure of the test specimen and the tensile strength of rock were compared and it showed that φ55 Ash and Oak exceeded the range of average tensile
strength of the target rock, and in the test specimen hydrating sodium hydroxide aqueous solution appeared to have exceeded the average tensile strength of the rock in the whole test specimen excepting Maple. When compared with the swelling pressure of expansive demolition agents, the test specimen that containing tap water appeared to be inferior to the swelling pressure of demolition agents, but in test specimen containing hydrating sodium hydroxide aqueous solution, φ55 Ash & Oak and φ50 Ash appeared to be similar or superior to the swelling pressure of demolition agents. Provided the swelling pressure of test specimen should be similar to the strength of rock or the swelling pressure of demolition agents, as a realistic demolition requires very high swelling(expansion), Ash seems to be able to act as a demolition material for boulder blasting in demolishing rock.
