Synthesis of Ambient Cured GGBFS Based Alkali Activated Binder Using a Sole Alkaline Activator: A Feasibility Study

Utilisation of industrial waste-based material to develop a novel binding as an alternative Ordinary Portland Cement (OPC) has attracted growing attention recently reduce or eliminate the environmental footprint associated with OPC. This paper presents experimental study on synthesis and evaluation alkali activated Ground granulated blast furnace slag (GGBFS) composite using NaOH solution alkaline activator without addition silicate solution. Different concentrations were used produce varied GGBFS based composites that evaluated for Uncofined Compressive Strength (UCS), durability, leachability, microstructural performance. Alkali prepared 15 M at 15% L/S ratio achieved UCS 61.43 MPa cured 90 days ambient temperatures. The results revealed formation zeolites, dense non-porous morphology. can be synthesized sole potential CO2 emission. metal leaching tests there are no pollution threats posed by long-term use.
