Research activity
Research activity
Research Activity of group coordinated by
Proff. Cristina Leonelli and Isabella Lancellotti, is
focused on formulation and characterization of
geopolymers, aluminosilicate materials obtained
by alkaline activation of natural or wastes
powders. Chemical stability and leaching of
metals are investigated in order to understand
the consolidation mechanism and raw materials’
reactivity.
Context and motivation of
the research
Geopolymeric paste is obtained at room T
without or with very low CO2 emissions with
respect to cement formulations. Geopolymers
have high chemical stability, therefore can be
considered a sustainable material useful also
for toxic waste encapsulation. Toxic cations can
be chemically and physically bound in the 3D
aluminosilicatic network.

Geopolymer Group
Impact on society
In 2008 an Italian Working Group on Geopolymers
was born within the Italian Ceramic Society. It is
coordinated by Prof. Leonelli with the aim of sharing
knowledge on these novel materials to address
industry towards them. Products of the research are
scientific publications congress attendances, projects
participation, patents, etc.
National and international
academic relationships regarding
the activity
Numerous national collaboration are active since
2008 as well as international contact and researchers/
students exchange with ZAG (SLO), University of
Oulu (F), University of Barcellona (E), Kasetsart
University (Thailand), MIPROMALO (Cameroon).
Joint international meetings, workshops, seminars and
schools are organized worldwide by the group at DIEF.
