Abstract:
Meta-materials are defined as nano-engineered materials that possess advanced processing, enhanced properties, and superior performance. Such properties are unprecedented and not possible to achieve with conventional approach. This paper reviews the development of several meta cement-based materials achieved by nanomodification technique, including the nano-engineered C-S-H gel, nano-engineered surface treatment and nano-engineered carbon nano fibers (CNT and CNF) Results on the durability of surface treated cement-based materials reflects advantages of meta-cement-based materials regarding their performances under severe environments. Such approaches open new directions on cement/concrete research.
