NS Nano silica in concrete ppt - Silica Fume for Sale .

Nano silica (also named as nano-silicon dioxide) is a kind of inorganic chemical material, commonly known as white carbon black. Because of its ultra-fine nano scale and its size range of 1-100nm, it has many unique properties, such as optical properties against ultraviolet, which can improve other materials’ anti-aging, strength and chemical resistance.

Effect of Nano-Silica in high performance concrete .

2020-7-23  Inclusion of nano silica up to 4% in concrete specimens increased mechanical properties at all ages. This is due to formation of hydrated products and pore filling effect of nano material. Usage of nano scale size particles can result in dramatically improved properties from conventional grain size materials of same chemical composition.

AbstractIntroductionAddition of Nanosized and Nano-Structured MaterialsUse of NanoreinforcementsApplications in Steel Structures, Joint and WeldsApplications in WoodConclusionReferencesNanotechnology is one of the most active research areas that include a number of disciplines including civil engineering and construction materials. Nanotechnology is the understanding, control, and restructuring of matter on the order of nanometers (i.e., less than 100 nm) to create materials with fundamentally new properties and functions. Nanotechnology encompasses two main approaches: (i) the ‘‘topdown” approach, in which larger structures are reduced in size to the nanoscale while maintaining t
