A study on the potential of polystyrene lightweight aggregate in concrete

Economic reason caused the used of expandable polystyrene increasing every year. The consequence is that the polystyrene wastes also mounted day by day. On the other hand, the source of natural aggregate is non-renewable. Public awareness to save the environment is always be campaigned through all k...

This research comprised the effort to produce lightweight aggregate concrete from waste expandable polystyrene or also known as polystyrene foam that can be found easily around our neighborhoods as electronic packaging.

In this work, the polystyrene lightweight aggregate product was incorporated in concrete. Concrete characterization was conducted similar to those for aggregate with additional the slump test, compression test and flexural test. The results showed that the best temperature to produce aggregate with highest compressive strength 69.2 MPa was 170°C where the water absorption levels only 2.4% and its bulk density 154.6 kg/m3.
