This paper aimed to analyze the relationship between flexural strength, elastic modulus, capillary absorption, bond strength, and compressive strength of engineered cementitious composite (ECC). For this purpose, sufficient data on the mechanical properties and durability characteristics of ECC produced by a high volume of natural pozzolana (NP) were developed. The experimental results showed that the incorporation of high volume of NP worsened the mechanical properties and durability characteristics of ECC mixtures as well as the bond strength between ECC overlay and concrete substrate. The results also show a strong correlations between compressive strength and the selected properties. This means that the selected properties could be predicted from the compressive strength values.
