Resumo
Results of axial rupture by compression of cylindrical cement paste samples are presented. This is part of a
research on cement paste behavior aiming at investigating the durability of cementitious materials in the
environment of repositories for radioactive waste. Portland cement paste is intended to be used as a backfill in a
deep borehole for disposal of sealed radiation sources which concept is under development. The service life of
the engineered barrier materials plays an important role in the long term safety of such facilities. Accelerated
tests in laboratory are being used to evaluate the performance of cement paste under the temperature expected at
some hundred meters below grade, under exposure to the radiation emitted by the sources, and under the attack
of aggressive chemicals dissolved in the groundwater, during the millennia necessary for the decay of the most
active and long-lived radionuclides present in the waste. The large variability in results of mechanical strength
as measured by axial compression of cylindrical samples is the subject of this short communication.
