How does it work?
The normal tensile strength of rocky materials is 4-10 MPa and that of concrete is 2-4 MPa. After applying CRACKOPEN to pre drilled holes of target site, it leads to exothermic reaction and hydration. Pressure gets built at target site owing to expansion of CRACKOPEN. Pressure exceeds well over 50 MPa ( (500 kg / cm2 ) which is far more higher than the tensile strength of the targeted stone and concrete thus causing it to crack and open itself without the need of an explosive; in a silent manner without any sound pollution.
The crack time of CRACKOPEN is 30 minutes to 24 hours after the completion of application.
The speed of crack opening is determined by the reaction speed which depends on temperature of the work site. Reaction time is shorter at higher temperatures. Reaction time is slower at higher altitudes owing to lower pressure.
