Engineered cementitious composite (ECC) is a high-performance fiber reinforced composite with high ductility which exhibits strain-hardening and multiple-cracking behaviour. The relative high cost remains an obstacle for wider commercial use of ECC. The replacement of cement by supplementary cementing materials (SCMs) and the use of local aggregates can lead to greener ECC with lower cost. This paper investigates the fatigue flexure performance of specimens made with ECC mixtures produced by incorporating micro-silica/local crushed sand with class F fly ash (FA). The results showed that ECC specimens produced with crushed sand exhibited strain hardening behaviour with deformation capacities comparable with the standard micro-silica sand. ECC specimens with silica sand developed more damage under fatigue loading of up to 400000 cycles due to higher deflection evolution than FA-ECC mixtures with local crushed sand. The study demonstrated the viability of producing greener, sustainable and cost-effective ECCs using locally available aggregates and fly ash of up to 70% of total cementitious material.
