The assessment of the mechanical properties of steel bars in existing reinforced concrete is crucial as much as the estimate of concrete strength. Till now no Non Destructive Tests (NDT) or Moderately Destructive Tests (MDT) have been developed to this aim. In this paper the Leeb durometer is applied to reinforced concrete (r.c.) steel bars...

A crucial aspect of the assessment of existing r.c. structures is the efficiency of the anchorage of the bars. This is specifically true for historic pre-code concrete, when the basic principles of r.c. structures were either not well understood nor set in a code practice. This is true also for the Hennebique-type structures that make use of a...

Cement is the most-used construction material worldwide. Research for sustainable cement production has focused on including nanomaterials as additives to enhance cement performance (strength and durability) in recent decades. In this concern, graphene is considered one of the most promising additives for cement composites. Here, we propose a...
