Mechanical performance of lightweight brick at elevated temperature
This study presents the production of lightweight concrete brick containing Expanded Polystyrene (EPS). The objective of this study is to determine the effectiveness of EPS as a substitute for sand in the concrete mix. The replacement percentage of EPS is 20%, 30%, 40% and 50% from the sand volum...

Summary: | This study presents the production of lightweight concrete brick containing Expanded
Polystyrene (EPS). The objective of this study is to determine the effectiveness of EPS as a
substitute for sand in the concrete mix. The replacement percentage of EPS is 20%, 30%, 40%
and 50% from the sand volume. Hardened brick density, compressive strength, water
absorption and fire resistance test were conducted in order to examine the brick performance.
The dimension of the brick is 215mm x103mm x 65mm. The total of samples for different testing
were 60 samples of bricks where 30 samples were undergoing for density and compressive
strength test with curing age 7 and 28 days, 15 specimens for water absorption test and 15
specimens for fire resistance test required. All brick samples were subjected to air curing. From
the results, it is found that brick sample with 50% EPS is considered as lightweight brick
because its density is 1435.71 kg/m3. The results indicated that increasing the volume of EPS
causes significant reduction to compressive strength, water absorption and fire resistance of
brick. |
