Production and Utilisation of Artificial Coarse Aggregate in Concrete - A Review

Abstract

This present work provides a study of several successful approaches in producing artificial aggregates using a pelletiser machine and the parameters affecting efficiency. These aggregates were contrived from substances of nature such as fly-ash, GGBS, Rice husk ash, volcanic ash, etc. Different sets of artificial aggregates are to be made with different molarity. The common methods of developing them include cold bonding, autoclaving, and sintering. The aggregate pellets (with lightweight and possessing less specific gravity and high impact value than gravel) were batch manufactured by a cold bonded technique using disc pelletiser (used to perform agglomeration). The prepared aggregates are characterised based on their crushing and impact strength rate and also moisture absorption. This paper explicitly reviews various effective and eco-friendly artificial aggregate and their potential usage in the construction industry.
