INFLUENCE OF REAL CRACKS ON CHLORIDE DIFFUSION

Abstract

The novelty of this study consists in using drilled cores from a large scale OPC reinforced slab, exposed to a simulated accidental failure of the central support and subsequent vertical loading until collapse, in order to determine the influence of real cracks in concrete structures on the penetration of chlorides. The experimental results were obtained with the non-steady state migration test described in NT BUILD 492, using an electrical field and real cracks. In order to study both the influence of rebars and cracks, reference samples were used. The chloride penetration depth was measured with a colorimetric method on each specimen. From these penetration profiles the influence of cracks on the penetration depth and the diffusion coefficient is investigated considering the crack patterns.
