Analyses
- Characterisation of the original render materials, with in loco experimental tests, to define the restoration mortars’ properties;
- The former cathedral of Elvas was part of the Cathedral Project (Characterization and Conservation of Traditional Historical Mortars of Religious Buildings in Alentejo), conducted by LNEC; UÉ; FC-UL and MC-DRE.
R&D
Investigation of traditional technical solutions for the formulation and application of mortars with raised joints for the plastering of the pyramid spire.
