| Summary: | Pepper waste can be reprocessed with clay to produce useful materials for pavement
purpose. The objective of this study is to investigate the mechanical properties of water
penetrable bricks made from pepper waste. Due to the nature of the material, pore-forming
ability of pepper waste was investigated. In order to compare the results, different ratios of
the pepper waste (0%, 2%, 5%, and 10% by mass) were mixed with clay and fly ash. Then,
all the brick samples of different compositions were moulded, dried and lastly, fired at 900
ºC. The water absorption, penetrability and compressive strength of the fired bricks were
tested and compared with standard specifications. The brick samples have water absorption
between 18.41% – 29.05%, penetrability rate as fast as 5.278×10-10 m3
s
-1 and compressive
strength between 6.17 MPa – 30.81 MPa. The compressive strength for all samples passed
the minimum requirement by Malaysian Standard for the ordinary quality clay brick, which
is not less than 5.2 MPa. The results showed that pepper waste addition would produce
porous bricks with satisfactory mechanical properties. |
