A carbon nanotube (CNT), on the other hand, has outstanding mechanical properties with a tensile strength of 63 GPa and Young's modulus of 1 TPa, making it a candidate as nano-scale reinforcements in OPC. Past research studies have reported improved mechanical and electrical properties of carbonnanotube-ordinary Portland cement (CNT-OPC) composites, which show future promise in practical civilengineering applications. In this study, recent research studies in developing CNT-OPC composites are comprehensively reviewed. Highlighted herein are the considerable efforts been made in the study of fabrication, hydration, porosity and transport properties of the CNT-OPC composites. There are, however, future investigations needed to provide a better understanding in the areas of uniform dispersion of CNTs within the OPC paste, durability, impact, fatigue properties and the theoretical modelling of CNT-OPC interaction. © 2011 Copyright Taylor and Francis Group, LLC.||Source Title:||IES Journal Part A: Civil and Structural Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/68160||ISSN:||19373260||DOI:||10.1080/19373260.2011.615474|
