4.6 Sources of further information and advice
Nano-science and nanotechnology have recently drawn considerable attention
from the scientific community in light of the potential applications of nano-
scale particles, whose high surface area-to-volume ratio translates into
exceptional chemical reactivity as well as unique physical properties.
Improvements in concrete performance have also been sought by resorting
to these new disciplines (Korpa and Trettin, 2008; Sanchez and Sobolew,
2010; Cardenas et al., 2011; Nina et al., 2012). One possible application of
nanotechnology is the manufacture of nano-pozzolans to raise the reactivity
of the original materials. Authors such Askarinejad et al. (2012) are studying
the manufacture of pozzolannano-structures from bulk natural pozzolans,
opening a new line of research based on natural pozzolans.
