EXPERIMENTAL INVESTIGATION ON BEHAVIOUR OF NANO CONCRETE

The influence of Nano-Silica on various properties of concrete is obtained by replacing the cement with various percentages of Nano-Silica. Nano-Silica is used as a partial replacement for cement in the range of 2.5%, 3%, and 3.5% for M 25 mix. Specimens are casted using Nano-Silica concrete. Laboratory tests were conducted to determine the compressive strength, split tensile and flexural ...

Nanoconcrete - Wikipedia

Nanoconcrete (also spelled nano concrete or nano-concrete) is a form of concrete that contains Portland cement particles that are no greater than 100 μm and particles of silica no greater than 500 μm, which fill voids that would otherwise occur in normal concrete, thereby substantially increasing the material's strength. It is a product of high-energy mixing (HEM) of cement, sand and water.
