The Cracking Effects of BreakQuik…
The Hydro-chemical reaction begins at once after mixing the BreakQuik with water. During the setting and hardening of this product a remarkable solid expansion occurs. This reaction can produce more than 300kg/cm2, of expansive pressure in the filled holes. Usually, the cracks appear between 8-24 hours after filling, depending on the amount of
BreakQuik used. The cracks will spread further and become wider and wider by time for about a week. The tensile stress which is created by more than 300kg/cm2 of expansive pressure that occurs inside the hole is much greater that the tensile stress of 20-40kg/cm2 in concrete and 40-100kg/cm2 in rock.
As the BreakQuik generates its expansive stress; the material to be cracked undergoes a process of
-
crack initiation,
-
crack propagation,
-
the increase of crack width.
Therefore, this fracture mechanism is distinguished from a breakage by blasting.
