Study on the Effect of Replacing Coarse Aggregate Partially with Polystyrene Beads in Concrete Mix

Deepika K. C., Raghavendra

Abstract: The demand for building materials is rising quickly due to the popularity of contemporary construction techniques. Finding substitute materials is crucial for advancing sustainable development. One such technique is to partially substitute polystyrene beads for coarse particles in concrete. These beads are leftovers from the packaging sector. In this study, traditional concrete blocks and concrete with polystyrene beads substituted are compared. The characteristics of hardened concrete were discovered to be impacted by the addition of polystyrene beads. Concrete of M15 grade was tested with coarse aggregate replacement rates of 10%, 20%, 30%, and 40%. Changes in compressive and flexural strength are evident in the results. Even with a low water-to-cement ratio, the mixes demonstrated high workability, which qualified them for use in construction.

Keywords: Polystyrene beads, Slump test, Compaction factor test, compressive strength and Flexural Strength
