Abstract

The use of waste materials from industrial products to support green building and environmentally friendly construction needs more attention and becomes a common thought. The use of waste materials such as Cement Kiln Dust (CKD) or often referred to as Bypass Dust (BPD), as a concrete substitution material, has been done a lot and not a few have given positive results. However, it is necessary to have other alternatives regarding using this waste material, one of which is to try to use it as a coating material for lightweight materials such as Expanded Polystyrene (EPS) to manufacture artificial aggregate. This coating technique uses a solvent/adhesive in the form of liquid (acetone–water and polyvinyl acetate-water). The resulting weights of coated EPS with BPD are 154–175 g/l. Artificial lightweight aggregate made from EPS grains coated with CKD powder with an adhesive solution of a mixture of Polyvinyl Acetate (PVA)-water gave more promising results than an acetone–water binder. The process of creating coated EPS shows the potential as artificial aggregates for a lightweight concrete. The coated EPS gives a better result in strength than pure EPS beads when replacing the coarse aggregate.
