  • Nanoconcrete Wikipedia

    Nanoconcrete (also spelled nano concrete or nanoconcrete) 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 also a product of highenergy mixingSEM micrographs show better packing density in the nanoconcrete at 90days of curing EDS shows that addition of optimal nS dosage in concrete led to formation of more CSH gels at 90days curing period, and a corresponding reduction in Ca/Si ratio of the nanoconcrete to 089; a ratio that is very close to that of 14Ǻ tobermorite reported in literature The optimal nanoEFFECT OF NANOSILICA ON THE MECHANICAL AND09/03/2022· Tables 7 and 8 show that increasing the nanosilica content reduced the water absorption of both concrete samples After 10 min, the inclusion of 1%, 2%, and 3% nanosilica content to M 30 grade concrete resulted in a reduction in water absorption of 515%, 3015%, and 3566%, respectively, compared to the control mixInfluence of nano silica on durability properties of concrete
