摘要:
Soundless cracking demolition technology is an essential method for demolition of buildings in place of engineering blasting in complex environments. However, the temperature dependence of soundless chemical demolition agent (SCDA) dramatically restricts the development and application of this technology. For this reason, the enhanced effect of subsequent heating on the expansive pressure of SCDA is examined in this study. A self-propagating heating tube was designed. After determining the optimal heating time through uniaxial compressive stren...
