Non-destructive or micro-destructive in situ tests are very relevant to the physical characterization of materials used in historical buildings. “Controlled penetration,” “sphere shock,” and “sonic methods” can be used to ...

The use of superabsorbent polymers (SAP) is effective in controlling internal desiccation of cementitious materials with low W/C. Until now, the use of this type of products is limited to research and special applications. ...

A cristalização de sais solúveis é um dos principais mecanismos de degradação dos materiais de construção porosos como a pedra, as argamassas e os cerâmicos. Este artigo foca a influência que o substrato poderá ter no ...

This paper describes the investigation carried out to address existing concerns about the reliability of bonded-in rod joints used in the rehabilitation of timber structures. The investigation assessed the influence of ...

While accessing the drying behaviour of sixteen (water borne) paint coatings applied on air lime mortar substrate, we found a surprisingly good (linear) correlation between the drying index (DI) and vapour permeability ...

This communication is based on a work done in LNEC, which consisted in the study of the protection performance of varnishes applied in wood surfaces for exterior exposure. The objective of this work was to evaluate the ...

Nesta comunicação é apresentado o trabalho experimental desenvolvido no LNEC, maioritariamente no âmbito do projecto Europeu LICONS – Low Intrusion Conservation Systems for Timber Structures, ter-minado recentemente, ...

The protection performance of varnishes applied to two different wooden substrates (maritime pine and iroko) for outdoor exposure was investigated for eight different varnish systems (with and without colorants and two ...
