DESCRIPTION:Cementitious composites are the most widely used c
 onstruction materials\nwith 4.1 billion tonnes of 
 cement being produced globally in 2017.\nHowever\,
  cement production is associated with ~7% of the t
 otal global\nanthropogenic CO2 emissions. Moreover
 \, concrete structures suffer from\npoor durabilit
 y\, with a fifth of the total civil engineering ou
 tput in\nthe UK being spent on repair and maintena
 nce. The poor durability of\nconcrete structures n
 ecessitates frequent inspections and an enhanced\n
 structural monitoring regime. Despite the advancem
 ents in material\nscience over the years\, cementi
 tious composites remain passive\nstructural materi
 als and do not possess any functionalities.\n\nThi
 s research aimed to take advantage of emerging gra
 phene-related\nmaterials (GRMs) to solve the chall
 enges associated with concrete\ninfrastructure and
  to instigate additional functionalities that woul
 d\nmake the material smarter. The homogenous dispe
 rsion of GRMs was\ninvestigated in detail\, follow
 ed by their effect on the early age\,\nmechanical 
 and permeability performance of cement pastes and 
 mortars.\nThe use of GRMs to improve the electrica
 l conductivity performance was\nalso investigated\
 , with the aim to create electrically conductive\n
 networks in the composite that could then be used 
 to monitor changes in\nloading or damage\, by trig
 gering a self-sensing response. Finally\, the\nkey
  findings from a Lifecycle Assessment (LCA) study 
 that was undertaken\nto establish the sustainabili
 ty performance of a novel GNP-cement\ncomposite\, 
 will also be presented.
