Effect of carbonation on the linear and nonlinear dynamic properties of cement-based materials

Eiras Fernández, Jesús Nuño; Kundu, Tribikram; Popovics, John Sandor; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan (Society of Photo-optical Instrumentation Engineers (SPIE), 2016)

[EN] Carbonation causes a physicochemical alteration of cement-based materials, leading to a decrease of porosity and an increase of material hardness and strength. However, carbonation will decrease the pH of the internal ...
Studies on nonlinear mechanical wave behavior to characterize cement based materials and its durability

Eiras Fernández, Jesús Nuño (Universitat Politècnica de València, 2016-10-10)

[EN] The test for determining the resonance frequencies has traditionally been used to investigate the mechanical integrity of concrete cores, to assess the conformity of concrete constituents in different accelerated ...
The effects of moisture and micro-structural modifications in drying mortars on vibration-based NDT methods

Eiras Fernández, Jesús Nuño; Popovics, John Sandor; Borrachero Rosado, María Victoria; Monzó Balbuena, José Mª; Paya Bernabeu, Jorge Juan (Elsevier, 2015-09)

In this paper, we investigate the utility of vibration-based NDT tests to detect the subtle microstructural modifications and cracking damage in Portland cement mortars subjected to oven drying treatment. Both linear ...
