abstract = {recent years, there has been a growing
interest in one-part alkali-activated materials, which
utilize solid-form alkali activators, within the construction
industry. This approach is becoming popular
due to its simpler and safer application for cast-in-situ
purposes, as compared to the conventional two-part
method. At this purpose, we have pioneered the use
of volcanic deposits of Mt. Etna volcano (Italy) as
precursor for the synthesis of a unique one-part formulation.
This was done to assess its performance
against both traditional and two-part alkali-activated
materials. The study employed a comprehensive
range of investigative techniques including X-ray
powder diffraction, Fourier transform infrared spectroscopy,
hydric tests, mercury intrusion porosimetry,
ultrasound, infrared thermography, spectrophotometry,
contact angle measurements, uniaxial compressive
strength tests, as well as durability tests by salt
crystallization and freeze–thaw cycles. The key findings
on the studied samples are as follows: i) small
size of pores and slow absorption-drying cycles; ii)
satisfying compactness and uniaxial compressive
strengths for building and restoration interventions;
iii) high hydrophily of the surfaces; iv) lower heating
dispersion than traditional materials; v) significant
damage at the end of the salt crystallization test;
vi) excellent resistance to freeze–thaw cycles. These
newly developed materials hold promises as environmentally
friendly options for construction applications.
They offer a simplified mixing process in
contrast to the conventional two-part alkali-activated
materials, thus providing an added advantage to this
class of materials.},
