DESCRIPTION:Traditionally\, cementitious blends have been employed in engi
 neering \napplications either as remedial works or part of the permanent \
 ninfrastructure. Although the design has a built-in redundancy for \nstruc
 tural safety under a variety of adverse events\, over the long-term\, \nre
 pair and eventual replacement has been inevitable. A solution has been \np
 roposed in recent years through the development of a new breed of  \n“sm
 art” cement. This material has the ability to respond to damage and \nre
 cover functionality\; namely heal itself.\n\nAim of this research was to i
 ntroduce this self-healing design approach \nto traditional blended cement
  suspensions\, assess their self-actuating \nrecovery potential and furthe
 r enhance it through the addition of \nrepairing agents. To achieve the la
 tter\, micron-sized polymeric capsules \nwere developed and characterised.
  These microscopic capsules were \ndesigned to deliver repair agents that 
 target known areas of stress \nbuild-up inside the composite matrix. The p
 roposed composite system was \nevaluated and the self-healing concept conf
 irmed.\n
