Abstract
The approach of combining the accelerator and VEA was found to be an effective means to increase the washout resistance and the rate of expansive pressure development of modified SCDA while retaining a reasonable flowability of SCDA. Finally, the study proposes an optimum combination of VEA (welan gum, 0.1%) and the accelerator (CaCl2, 2%) by weight of SCDA to produce an SCDA with enhanced expansive pressure generation in submerged conditions, which can be effectively and safely applied for demolition and rock fragmentation.
