“…From Figure 11, it is clearly seen that the relative compressive strength increases as a function of the dosage in all curing ages, with the maximum values produced by the dosage of 3%. This consequence is confirmed to other similar researchers reported by Nazari and Riahi [24] and Singh et al [25]. It could be explained by the so-called filler effect or seeding effect; that is, additional surface area could offer more nucleation sites.…”

“…The next significant decline was detected between 400 and 550 °C, which can be linked to the CH dehydroxylation. The fourth and final decay was due to calcium carbonate, and clinker carbonation was found between 600 and 800 °C [ 46 , 47 ].…”

“…Among the nanoparticles used in cementitious materials, the nanosilica stands out. The nanoparticles of silica (nanosilica) have superior reactivity when compared to the particles of the same chemical composition and of larger size, such as the silica fume (Puentes et al 2015;Nili et al 2015;Singh et al 2015a;Chen et al 2016, Alonso-Rodriguez et al 2017, as well as accelerate cement hydration reactions (Singh et al 2015a, Singh et al 2015b, Hou et al 2015, Singh et al 2016, Moon et al 2016. The C-S-H formed is more polymerized and has longer chains , Moon et al 2016.…”

“…at 2 days. This is probably due to the pozzolanic reaction of NS and to the accelerating effect of NS on cement hydration (Seekkuarachchi et al, 2008, Sanchez del Bosque et al, 2015, Singh et al, 2016, but also indicate the better synergism between MK and NS.…”
