Engineered Cementitious Composites (ECC) was a concrete which incorporate fiber instead of steel reinforcement for higher ductility. The fibers provide pulling force between crack thus preventing the crack to grow and multiple. Although it was handy in usage for repair work and construction due to its ductility, the high cost and high environmental burden during production was still a shortfall to overcome for it to be cost effective and sustainable. In previous study, Recycled Concrete Fines (RCF) replaced the uses of aggregates in concrete mixing reducing its cost and usage of raw earth material, sands. In this project, another recycled material, Ground Granulated Blast Furnace Slag (GGBS) to substitute certain percentage of cement. 80% GGBS was mixed with varies size and proportion of RCF was designed and properties tested according to varies tests. The tests include compression, 4 point bending and resistance measurement on its mechanical properties.
