[[Nanoconcrete]] (also spelled "nano concrete"' or "nano-concrete") is a class of materials that contains Portland cement particles that are no greater than 100 μm<ref>{{cite book|chapter-url={{google books|plainurl=y|id=eRVAAAAAQBAJ|page=485}}|title=Proceedings of the International Symposium on Engineering under Uncertainty: Safety Assessment and Management (ISEUSAM-2012)|last1=Tiwari|first1=AK|last2=Chowdhury|first2=Subrato|date=2013|publisher=Springer India|others=Cakrabartī, Subrata; Bhattacharya, Gautam|isbn=978-81-322-0757-3|location=New Delhi|page=485|chapter=An over view of the application of nanotechnology in construction materials|oclc=831413888}}</ref> 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.<ref>{{Cite journal |last1=Thanmanaselvi |first1=M |last2=Ramasamy |first2=V |date=2023 |title=A study on durability characteristics of nano-concrete |journal=Materials Today: Proceedings |volume=80 |pages=2360–2365 |doi=10.1016/j.matpr.2021.06.349 |issn=2214-7853}}</ref> It is widely used in foot and highway bridges where high flexural and compressive strength are indicated.<ref name=raju/>
