| description | This project was carried out to investigate the mechanical and durability properties of
hardened polystyrene concrete bricks containing sawdust ash. In this study, polystyrene
beads as lightweight aggregate are used to replace fine aggregate in the concrete mixture
whereas sawdust ash is for replacement of cement. A total of 216 bricks with the size of
195 mm x 100 mm x 65 mm (length x width x height) were prepared. Six tests were
carried out to investigate and compared the properties of polystyrene concrete bricks.
The tests were compressive strength test, water absorption, sea water attack, weight and
density, dimension and acid attack. The compressive strength of bricks was depended on
the materials mixed and the ratio used. Although higher ash content decreased the
strength of concrete, the test result indicated that sawdust ash can contribute strength to
concrete at longer curing periods. The bricks tested in sea water were compared with the
bricks tested in tap water. The result shows the bricks with low weight and density
recorded high water absorption rate. Sawdust ash also influenced the water absorption as
it is a good water absorbing materials. The bricks tested in sea water recorded lower
compressive strength than bricks tested in tap water. The bricks tested in acid attack also
show changes in physical properties such as appearance, weight and density and
dimension. The changes of properties of polystyrene concrete bricks are much higher
for high content of polystyrene beads and sawdust ash in the mix. |
