  • Appliions of using nano material in concrete: A review

    Nano alumina is formed from alumina itself. There are limited studies reported on the use of nano alumina in concrete. The addition of nano alumina in concrete especially UHPC can hugely affect concrete properties as it controls the setting time of cement. The function of nano alumina in cement is to speed up the initial setting time for UHPC.
