Fire behaviour of mortars with portland cement and residual diatomaceous earth Conference Paper uri icon


  • The high pollution levels produced by the manufacturing of conventional Portland cement have motivated several studies in an attempt to modernize this process with alternative binders and the conscious use of natural resources. The correct treatment of residues has become a matter of great concern. The project “BacchusTech” aims to reuse diatomaceous earth from wine filtrations, introducing them into the composition of cement mortars through the reduction of cement and sand, seeking to valorise this winemaking residue and contributing to a sustainable construction. Three compositions of Portland cement-based mortars introducing residual diatomaceous earth are studied and fire behaviour tests are performed to the obtained specimens of mortars. The characterisation of these elements regarding their reaction to fire is performed using the cone calorimeter equipment.
