Multi-wall carbon nanotubes (MWCNTs) exhibit exceptional mechanical and electrical properties can be used to improve the piezoelectric of cement-based materials. In present study, effect different MWCNT concentrations as well types surfactants a superplasticizer were examined reinforce, at nanoscale, white cement mortar typically for restoration monuments cultural heritage. It was shown that sodium dodecylbenzenesulfonate (SDBS) Triton X-100 slightly decreased mortars' resistivity (by an...

The present article investigates the effect of superplasticizer and graphene nanoplatelet addition on flexural electrical behaviour nanocomposites for applications related to restoration/conservation Cultural Heritage Monuments in laboratory scale. Graphene nanoplatelets’ is used transform matrix into a piezo-resistive self-sensor by efficiently dispersing electrically conductive nanoplatelets (GnPs) material create paths. Nevertheless, appropriate dispersion difficult be achieved as GnPs...
