Non-standard testing in characterisation and consolidation assessment of historic mortars

Abstract

Non-standard tests are carried out on specimens made of materials extracted from historical objects, and they typically have non-standard dimensions. Assessments of strengthening effects are also usually studied on non-standard specimens purposely designed and made of materials modelled on the historic materials. The tests themselves are destructive, as engineers prefer destructive tests on a real material for a better understanding of the real material's behaviour. Destructive tests provide a better opportunity to acquire data for numerical modelling and for following the gradients of qualities, namely after consolidation interventions. The tests include compression tests, bending tests, shear tests, and a series of tests on specific specimens designed for studies of consolidation effects. © RILEM 2012.
