Abstract
A prevalent variant of lightweight concrete is the type that incorporates Expanded
Polystyrene (EPS) as part of its primary aggregate. Despite its lightweight nature,
the utilisation of EPS material have a detrimental impact on the overall quality of
concrete, particularly in terms of its compressive strength. A non-destructive test
method using an Ultrasonic Pulse Velocity (UPV) meter used in this study to
determine the density of lightweight concrete with EPS aggregate beads. The
comparison between normal concrete, uncoated, and coated EPS beads, with Fly
Ash powder as a coating material as Polyvinyl Acetate (PVA) as the binder. The
findings of this study indicate that incorporating EPS as a concrete aggregate
reduced the speed of travel of ultrasonic pulse waves. This reduction in this pulse
confirmed by a decrease in the overall strength of lightweight concrete compared
to normal concrete as control. However, interestingly, using modified EPS beads
in concrete resulted in better results than using uncoated EPS beads.
