Abstract
In this work, an investigation was carried out to assess the use of pH sensitive encapsulation for carbonation triggered release of Sodium Monofluorophosphate (NaMFP) - an inorganic healing agent. To do so, a state-of-the-art review of pH sensitive wall material and a technique to fabricate the same, to encapsulate NaMFP, was performed. The outcome of comparative analyses conducted on prospective shell materials and encapsulating techniques yielded three potential shell materials and two possible techniques. These findings can aid in future experimental investigations to scale up the use of such encapsulation technologies in the construction sector. This would contribute to the research in producing smart cementitious materials that can detect minute changes in their environment and performtargeted healing, without the need for human intervention.
