In the paper the main results of numerical study presented in Gambarelli et al. [1] on concrete elements confined by carbon fiber reinforced polymer (CFRP), are overviewed.
Most of the analysis oriented models are derived from the stress-strain relationship proposed by Popovics [13,14] and reformulated by Mander et al. [15].
By means of DP potential function the model proposed by Rousakis et al. [18] was reviewed by Yu et al. [21], which proposed a modified DP type of plasticity model in order to correctly predict the behaviour of both actively confined and FRP confined concrete.
These data, such as the majority of the experimental tests available in the literature (Nisticò et al. 2014) [22] refer to plain concrete.

Batori et al. [2] developed biocomposite materials using OW, reinforcing a matrix of pectin and hemicelluloses with cellulose; further, the hypothesis in this study was that ultrafine friction grinding of OW would result in homogenisation and cellulose fibrillation, improving the material’s mechanical strength.

Kinetics of Adsorption
The kinetics of adsorption of dye by CAC, RAC, CSC and SDC have been studied by testing the applicability of the first order kinetic equations proposed by Natarajan – Khalaf [38], Lagergren – as cited by Pandey et al [39] and Bhattacharya and Venkobachar[40].

Based on the spectrum, the band at 463 cm-1 is attributed to T-O (T = Al or Si) bending vibration [9].
In addition, the shifting of the band to lower wavenumbers is also due to weaker Al-O bonds than Si-O bonds [12].
Previous research by Liu et al. [17] on fly ash as alkali-activated binder also detected this peak [17].
Furthermore, the shift to a lower wavelength is due to the polycondensation process of Si-O and Al-O bonds in the alkaline environment during depolymerization of the amorphous phase of fly ash to Si-O and Al-O bonds, which consequently causes decrement in intensity [15].
