Abstract: Fly ash is a fine powder produced by coal combustion in thermal energy plants before the release of gas into the atmosphere. This industrial by-product may be below the standard building materials, but it is advantageous to good performance because of its low cost. This study reviews the literature to investigate the properties and improvement of fly ash/fibre as a concrete substitute compared to fibre, silica fumes, cocoon fibres and other agents. Furthermore, because fly ash is widely considered as a concrete pozzolan, it will open the way for more sustainable solid waste management through industrial waste and sustainable materials combined with organically available plant materials such as cocoa and rice husk.

Keywords: concrete; coconut fibre; fly ash; moisture content; sustainable concrete.
