ROCKITE and KWIXSET are fast setting, hydraulic type cement compounds of more than twice the strength of fully cured conventional concrete. When mixed with water to pourable consistency they flow and seep into place as though they were molten lava. Both products have an initial set with in 15-20 minutes. With in one hour they will develop compression strengths of 31Mpa or 4500 psi. Its adhesion is due to expansion (hydraulic forces against exterior walls of drilled holes etc) and when fully set it grips metal to concrete permanently.
