Single and combined effects of nano-SiO2, nano-Al2O3 and nano-TiO2 on the mechanical, rheological and durability properties of self-compacting mortar containing fly ash

RETRACTED: Effect of nano-CuO and fly ash on the properties of self-compacting mortar

“…However, most of them have focused on using nano-SiO 2 (NS), nano-TiO 2 and nano-Fe 2 O 3 (NF) particles [15][16][17][18][19][20][21][22][23]; only few studies have been conducted on the potential of using copper oxide (CuO) nanoparticles in construction materials [17,24]. Copper oxide (CuO) can be found in dusts and galvanic sludge recovered after treating gas in areas which use scraps as raw materials, such as in steel factories and foundries [18].…”

Effect of Nano-Alumina on Pore Structure and Durability of Class F Fly Ash Self-Compacting Mortar

“…Moreover, NA particles improve the density and homogeneity of the cement matrix by providing a better distribution of C-S-H and by restricting C-H crystal growth, which may lead to the blockage of existing pores and hence the change the pore structure . Furthermore, it can be concluded that the increasing pore volume of mortars after the addition of 5% NA is caused by the nonuniform distribution of nanoparticles in the mortar matrix, resulting in agglomeration and production of more internal pores (Mohseni et al, 2015c).…”

Durability Properties of High-Performance Concrete Incorporating Nano-TiO₂ and Fly Ash

“…Most of the studies found, have been conducted with nano-SiO 2 (Du et al, 2014;Hou et al, 2013) in cement-based materials. Recently, the effects of other nanoparticles, such as nano-Al 2 O 3 , nano-TiO 2 , nano-CuO, nano-Fe 2 O 3 and nano-ZnO 2 on the physical and mechanical properties of cement-based materials were also investigated in a few studies (Mohseni et al, 2015a;Madandoust et al, 2015;Khotbehsara et al, 2015;Yang et al, 2015;Mohseni et al, 2015b). Publications on HPC containing nanoparticles are limited in the literature.…”
