Abstract

A spectroscopic investigation was carried out in order to determine the boron evolution into the structure of
fly-ash based geopolymers, integrated with borosilicate glass coming from pharmaceutical waste. Fourier transformed
infra-red (FTIR) spectroscopy was used to define the type of bonds after geopolymerization. Various
solid-state nuclear magnetic resonance (MAS-NMR) measurements were instrumental to evaluate the extent of
network formation in the structure and to compare the type of environments among the geopolymerization products
and the source materials. ⁠11B NMR conducted firstly on a pure borosilicate glass sample and then on a
geopolymeric sample evidenced a variation of the chemical shifts of the pattern, proving that boron oxide (B⁠2O⁠3)
initially dissolved and then took part in polycondensation reactions. FTIR spectroscopy showed the characteristic
peaks of a geopolymeric product, also proving that the effectiveness of the reaction was not affected by incorporation
of boron.
