“…The cement-based materials can be mixed with nanomaterials such as nano-silica (nano-SiO 2 ), nano-alumina (nano-Al 2 O 3 ), nano-ferric oxide (nano-Fe 2 O 3 ), nano-titanium oxide (nano-TiO 2 ), carbon nanotubes (CNTs), graphene and graphene oxide. In recent years, several researchers [29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49] have studied the incorporation of nanomaterials into cement-based materials. The mixture of cementitious composites and nanomaterials can increase the mechanical strength of the resulting concrete structures.…”
