Abstract:
Since an optimal compromise between structural and environmental requirements needs to be reached in building materials, to tailor a sustainable reinforcement of lightweight cement-based composites the so-called eco-mechanical approach can be adopted. Such a comparative analysis was performed on two plates used to retrofit the sidewalks of a famous bridge in Italy. In the first plate, made with expanded clay aggregates, the traditional steel bars were the reinforcement. Whereas only polymeric fibers reinforced the same lightweight concrete in the second plate. In all the cases, the reinforcements guaranteed strength and ductility, as required by code rules. However, the plates made with the fiber-reinforcement showed lower eco-mechanical performances than those reinforced with rebar.
