Abstract :
The aim of this work is to improve the physical properties (porosity) and mechanical performance (compressive strength) of the radioactive waste containment matrix, using silica fume as a cement substituent. The obtained results by the different elaborated formulations (2%, 4%, 6%, 8% and 10% of silica fume) show that the physical properties and mechanical performance of all the stated matrix have been improved. This improvement results to the pozzolanic and granular effects of the silica fume.
