Investigation of the mechanical, microstructural and mineralogical morphology of soundless cracking demolition agents during the hydration process

Abstract

Soundless cracking demolition agents (SCDAs) have emerged as a potential method for underground rock fragmentation. However, the application of SCDAs in deep earth formations requires them to be modified to suit each application. Basic understanding of the hydration mechanism and the expansive pressure generation of SCDAs is of paramount importance in the process of adapting SCDAs to such applications. Therefore, the microstructural, mineralogical and mechanical morphology of SCDA during the hydration process was studied through a series of experiments (Uniaxial compressive strength (UCS), scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis) carried out on SCDA specimens ..
