Analytical Model Will Improve Designs for Extending Concrete Life

Posted: Jul 20, 2022

Researchers at the University of Colorado Denver developed an analytical model that can be used to improve repair technique designs for concrete suffering from a common reaction between aggregate and Portland cement that can damage and weaken concrete over time. The researchers studied 120 concrete cylinders cast with and without confinement by carbon-fiber reinforced polymer using two types of aggregates to represent variable levels of alkali-silica reaction. The structural responses of the plain and confined concrete specimens were examined with an emphasis on load-carrying capacity, toughness, and failure characteristics. An analytical model was developed to complement the experimental findings and to propose design recommendations.
