Abstract


Objective:To develop geopolymer concrete (GPC) using 100% industrial waste as a binder at ambient temperature. Methods/Analysis:The low calcium fly ash based GPC was prepared with different percentage (0%,5%, and 10%) of alccofine and fly ash content (350,370,400kg/m3), to examine the fresh and hardened properties of alccofine activated GPC like density, workability, water absorption, permeable voids, water permeability, compressive and split tensile strengths using international standards. Nine mixes were prepared and investigated by X-ray diffraction (XRD) and Scanning electron microscopy (SEM) for the determination of their phase, composition and microstructural properties. Findings: The result shows that alccofine enhances the mechanical properties and significantly reduces the transport properties of GPC. Furthermore, GPC specimens prepared with alccofine emerge to improve the densification process. The results of investigations conducted reveal that higher percentage of alccofine and fly ash content has a significant effect on the polymerisation of the GPC, which in turn improves the strength and microstructural features. A maximum compressive strength of 42 MPa is achieved with 10% alccofine without elevated heat curing. Novelty/Improvement:Alccofine plays a significant role in improving the mechanical and transport properties of low calcium fly ash based geopolymer concrete at ambient conditions providing as an alternative to heat cured GPC.
