Abstract

A procedure to increase the compressive strength of concrete consists of its confinement by carbon fiber fabrics bonded externally with epoxy resins. In this way, a structural system is obtained that increases in a very remarkable way its resistance and ductility with respect to the base material. There are different models to estimate the compressive strength of confined concrete. All these models have been experimentally calibrated and in them the characteristics of the confinement material intervene. However, they are not able to predict in a solvent way the effect of the confinement when the concrete moves in a fork of important resistances. In this work, the compression resistance of concrete of low and medium resistances confined with carbon fiber fabrics has been evaluated experimentally. Different existing models have been analyzed to predict the strength of confined concretes and the experimental results obtained have been compared with the values estimated by the models of these documents. The analysis of the results allows to identify the models that best fit the experimental values obtained.
