In shattering hard rock or military defences, high brisance generally is necessary, so high explosives with extremely high detonation velocity are used as far as is practical. One of the most brisant of the conventional explosives is cyclotrimethylene trinitramine (also known as RDX or Hexogen). RDX is the explosive agent in the plastic explosive commonly known as C-4, constituting 91% RDX by mass.
