anotechnology continuously reshapes our world, redefines and enriches

knowledge, while opening new horizons. Tailored construction materials have

become a reality and characterization techniques relating to all scales (nano-mi-

cro-macro) are being correlated. But what can nanotechnology offer in cement

science and how can we best utilize the available resources and expand them?

This talk provides an overview of the speaker’s latest achievements in the field

of cement science with the addition of specific nanoparticles. Silicon dioxide and

montmorillonite nanoparticles are scrutinized, new theories and methodologies

on how the dispersion medium and nanostructure of the particles can affect

the performance and characteristics of composite cement formulations are dis-

cussed. In light of the E U regulations on limiting the CO

2

emissions mainly caused

by the production of Portland cement clinker (PC), the research carried out breaks

the allowable minimum limits of PC addition in composite cement formulations.

The permissible maximum limits of additions such as fly ash, limestone and/or

silica fume according to EN 197-1:2011 are also broken by adding nanoparticles.

This breakthrough is allowing a twofold advantage in embodied CO

emissions

reduction and further financial savings. Denser microstructure, stronger and more

durable cementitious products are rendered possible. How can we best monitor

these changes? Of the various characterization techniques available, which can

be directly correlated? On top of all, what are the levels of confidence with respect

to the nanoparticles addition? Which are the controlling parameters and how can

we ascertain the benefit? In addition, could specific nanoparticles be suitable for

the structural restoration of historical listed monuments? All the above questions

will be answered through selected series of comparative results showing the en-

hancements offered by the addition of the nanoparticles and the difficulties en-

countered. The talk will be concluded with ideas on further research

Biography

Styliani Papatzani has completed three Master courses [Imperi-

al College and National Technical University of Athens (NTUA)]

with awards and distinctions. She has worked in industry carry-

ing out structural design of newbuildings and structural assess-

ments of existing buildings and monuments, then completed a

PhD on the effect of various nanoparticles in cement formula-

tions from the University of Bath, UK and Postdoctoral studies
