In 1965, a large pressure vessel (16m [52ft] long by 1.7m [5.6ft] in diameter), designed for operation at a gauge pressure of 350 bar, failed during pressure test at the manufacturer. The failure, which was of the brittle type, occurred at a gauge pressure of 345 bar, and four large pieces were flung from the vessel.

Epoxy injection is an economical method of repairing non-moving cracks in concrete walls, slabs, columns and piers and can restore the concrete to its pre-cracked strength. Allow the paste-over to harden before beginning injection. Note: CIP, CIP-F and ETR epoxies are fast cure, manually mixed materials and may harden prematurely if left in a mixed mass on the mixing surface while installing

After concrete is mixed and before it gets completely hard, it’s referred to as “plastic.” The most common cracks in plastic concrete are plastic shrinkage cracks and crazing. These are caused by the surface drying out faster than the underlying concrete—when the evaporation rate on the surface, due to dry or windy conditions, is greater than the bleeding.
