This paper reports results of strength and reaction products of blast-furnace slag cements activated using a mixture of MgO-NaOH with a ratio 50/50 incorporated at 4, 6 and 8% relative to the slag mass. Pastes and mortars were prepared and cured at 20°C and 60°C-24h-20°C up to ...
Influence of the relative importance of electrochemical polarization and chemical stability effects on the passivation processes are clearly critical factors for these Al-based CMAs. The following conclusions can be drawn from the detailed characterization of Al–Cr–Fe and Al–Cu–Fe–Cr CMAs surfaces...
In Fig.1b, the FTIR spectra of Cu (II) loaded on TRH exhibited changes in the peak positions and relative intensities. The shifting of peaks to 1026.8 and 501.4 and decrease in intensity of 1738.1, 1507.0, 1361.7, and 1216.3 cm−1were observed for TRH, which suggests that less stretchin...
After removal from the oven the obtained samples were kept in the climate chamber at a temperature of 23 °C and relative humidity of 50% and their flexural and compressive strengths were measured at 7, 14 and 28 days. Figure 1. Methodology used for the preparation of the geopolymer paste...
