Abstract

The aim of this research is to develop a novel self-healing system which involves hollow plant fibres to repair the concrete cracks. The hollow pant fibres are first modified in order to hold a large quantify of healing agent without giving healing agent up until destruction. When the cracks develop in the concrete, they will spread through the concrete, rapture the fibres and release the healing agent. The healing agent freed will react/cure with/within the concrete forming insoluble substances which fill out the cracks. By doing so, the mechanical properties of uncracked concrete will be regained.
