Expansive Response in Concrete Slabs Structure

Rozpinave reakce ve strukture CB krytu

Over the past years, hair thin cracks appear very early, in the initial stage within a few months or a couple of years after the concrete was laid, and subsequently develop aggressively, especially in case of cement concrete pavements (CC). Visible cracks arise primarily around joints at the edges and in the corners of concrete slabs; from there, they spread into the whole slab. This problem appears not only in the Czech Republic and Slovakia, but it occurs concurrently in Germany, USA and in other countries. As the problems are the same both on pavements with heavy traffic and without traffic, the reason seems to be grounded in technology. The cause is called expansive response in concrete. Despite significant effort on international level, no generally recognized methodology leading to successful diagnostics has been discovered. In this paper, one of new concepts of diagnostic research is introduced; it has been employed especially in diagnostics of airport pavements in Central Europe.
