Traditional methods for concrete structure demolition is not adequate specially for urban areas and historical places due to hazard of explosive and noise. Therefore, Soundless Chemical Demolition Agents (SCDA) is useful in urban area and historical places. In this study, a analysis for SCDA is performed depending on boundary conditions.

Traditional methods for demolition of rocks may not adequate specially for urban areas and historical places. Accordingly, an use of soundless demolition chemical agent (SCDA) increases in those areas. In this study, required expansive pressure of SCDA for initiating cracks in maritime bedrock was study. It was found that shape of hole and distance between holes reduced required expansive pressure up to 59%.

Traditional methods for demolition of concrete structures and rocks are jackhammer and explosives methods. However, these traditional methods may not adequate specially for urban areas and historical places. Accordingly, an use of soundless chemical demolition agent (SCDA) increases in those areas. SCDA is similar to portland cement and lime is a key ingredient. In this study, expansive pressure from the selected SCDA were measured using outer pipe measuring technique and crack length due to the SCDA were simulated using obtained test data.
