The present study attempts to obtain the critical strains in concrete induced on account of reinforcement corrosion by simulating the expansive pressure of corrosion products using grout. Surface strains induced in hollow concrete cylinders due to expansion of grout filled inside the hollow portion were continuously monitored to experimentally validate the well-known thick-walled uniform cylinder model used in reinforcement corrosion problems. The study shows that expansive grout could effectively simulate the internal pressure generated in accelerated corrosion tests, and can be used as a means of obtaining critical strains in relatively shorter duration in laboratory studies.

Abstract


The present study attempts to obtain the critical strains in concrete induced on account of reinforcement corrosion by simulating the expansive pressure of corrosion products using grout. Surface strains induced in hollow concrete cylinders due to expansion of grout filled inside the hollow portion were continuously monitored to experimentally validate the well-known thick-walled uniform cylinder model used in reinforcement corrosion problems. The study shows that expansive grout could effectively simulate the internal pressure generated in accelerated corrosion tests, and can be used as a means of obtaining critical strains in relatively shorter duration in laboratory studies.
