Abstract: 
Lack of durability has recognized a major concern in construction practices for the past decades. In order for safety requirements to be fulfilled, it is vital to know whether durability needs are ensured or not. One of the most severe concerns in the case of sharp decrease in durability associated with concrete cracking. Concrete may crack throughout the service life of a structure. The presence of cracks influence the mechanical properties and allows for aggressive ions to penetrate into concrete itself and reinforcing bars by creating additional pathways which can lead to further cracking and disintegration in time. Therefore, durability can be associated with the brittle nature of concrete. Engineered Cementitious Composites (ECC) is a special type of high performance fiber reinforced cementitious composites with substantial benefit in both high ductility and multiple micro-cracks as a result of mechanical loadings. In this document, emphasis is placed on the accumulated knowledge on durability performance of high volume fly ash incorporated (green - environmentally friendly) ECC under various types of aggressive environments and mechanical loading. The introduction of materials which provide both high ductility and promising durability can significantly impact the design of future, more durable infrastructures.
