Geopolymer concrete derived from industrial wastes has been innovatively used to increase ductility of precast concrete beams in a dual-layer casting approach. Laboratory investigations showed marked improvement of beam samples in toughness, post peak behaviour and ductility. This is also one of the first studies that utilise acoustic emission (AE) measurements in assessing fracture behaviour with good success. This study adds weight to further justifying the effectiveness of geopolymer concrete composites used in standard concrete structural members to achieved sustainability goals without sacrificing cost-performance, and suggesting the usefulness of AE technique for comprehensive fracture mechanics study of brittle materials.
