Diese Studie befasst sich in der ersten Phase mit der Bewertung der Auswirkungen des Anteils an natürlichem Puzzolan (PN) auf die mechanischen Eigenschaften und die Haftfestigkeit des hochduktilen Zementverbundstoffs CCHD, der für die Reparatur von Stahlbetonstrukturen bestimmt ist. In der zweiten Phase wurden die Biegeparameter mithilfe des 4-Punkt-Biegetests gemessen. Die experimentellen Ergebnisse zeigten, dass PN die mechanischen Festigkeiten von CCHD in allen Altersstufen verringert. Darüber hinaus erhöht die Verwendung eines hohen Anteils an natürlichem Puzzolan den kapillaren Absorptionskoeffizienten und die Schrumpfung signifikant und verringert die Haftfestigkeit. Es sollte auch beachtet werden, dass die Verwendung einer hohen Dosierung von PN die Verformungsfähigkeit von CCHDs signifikant verbessert. Gemäß den in dieser Studie erzielten Ergebnissen kann man schlussfolgern, dass CCHD aufgrund seiner mechanischen Eigenschaften, seiner angemessenen Dimensionsstabilität mit dem Substrat zusätzlich zu seiner hohen Duktilität ein ideales Material für die Reparatur ist.
