99Technetium (99Tc) is a hazardous radionuclide that poses a serious environmental threat.
The wide variation and complex chemistries of liquid nuclear waste streams containing 99Tc …

The potential position of and drivers for inorganic polymers (“geopolymers”) as an element
of the push for a sustainable concrete industry are discussed. These materials are alkali …

Ground granulated blast furnace slag (GBFS) has been used to alter the geopolymerisation
behaviour of fly ash. The influence of varying amount of GBFS (5–50%) on the reaction …

Massive growth in the infrastructure industry and development has led to a phenomenal
increase in cement usage. The cement industry emits the greenhouse gas (CO 2) and …

Abstract X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning
electron microscopy (SEM) and compressive strength measurements were performed to fully …

Alkali activation of fly ash by sodium silicate solutions, forming geopolymeric binders,
provides a potential means of treating wastes containing heavy metals. Here, the effects on …

This chapter discusses the different solutions that are used as activators in geopolymer
synthesis: alkali metal hydroxides and silicates. The phase behaviour, speciation and …
