La prima fase dello studio ha valutato l’effetto del contenuto di pozzolana naturale (NP) sulle proprietà meccaniche e sulla resistenza all’adesione del composito cementizio ad alta duttilità CCHD per la riparazione di strutture in cemento armato. Nella seconda fase, sono stati misurati i parametri di flessione utilizzando la prova di flessione a 4 punti. I risultati sperimentali hanno mostrato che la NP riduce le resistenze meccaniche del CCHD a tutte le età. Inoltre, l’uso di un alto livello di pozzolana naturale aumenta significativamente il coefficiente di assorbimento capillare e il ritiro, e diminuisce la forza di legame. Va notato anche che l’uso di un elevato dosaggio di NP migliora significativamente la capacità di deformazione dei CCHD. Sulla base dei risultati ottenuti in questo studio, si può concludere che il CCHD è un materiale ideale per la riparazione grazie alle sue proprietà meccaniche, alla sua adeguata stabilità dimensionale con il substrato e alla sua elevata duttilità.
