Effect of grog addition on local clay ceramic properties using extrusion method
Non-plastic material such as grog is widely used in brick, roofing and floor tile making. Grog is produced from ceramic waste that was recycling to be use as an additive in ceramic body system. With regards to the case in Ceramic Workshop, Kolej Kemahiran Tinggi MARA Masjid Tanah, the ceramic waste...

| Summary: | Non-plastic material such as grog is widely used in brick, roofing and floor tile making. Grog is produced from ceramic waste that was recycling to be use as an additive in ceramic body system. With regards to the case in Ceramic Workshop, Kolej Kemahiran Tinggi MARA Masjid Tanah, the ceramic waste after bisque firing process may arise due to daily activities or
production. Hence this study was carried out to determine the effect of grog to the local clay ceramic properties. Local clay original deposited from Sungai Petai village, Alor Gajah
Melaka incorporated with grog has been fabricated by using extrusion method and sintered at temperature 1200 °C. Since the grog is non-plastic material, the amount and particle size was optimized. Two parameter of grog that is percentage of addition varied from 0%, I 0%, 20% and particle size from coarser (2000 μm) to finer (200 μm) was studied. From the findings, it
is shown that amount of grog addition and its particle size has give the impact towards local clay ceramic properties such as plasticity, water absorption, apparent porosity, shrinkage and
compressive strength. From the plasticity testing, it is found that 0% grog has developed plasticity at lower water content. Deformability ratio and proportionality factor was decreased
with the increasing amount of grog and particle size makes it less plasticity. The physical and mechanical properties of local clay fired sample have been successfully studied. In lieu of
result findings, it is shown that 10% grog addition with finer particle size, 200 μm give the lowest percentage of drying and total shrinkage with 3.75% and 6.28% respectively, lowest
percentage of water absorption, 8.68% and apparent porosity, 18% compared to the others. In term of mechanical properties, I 0% grog addition with finer particle size has shown highest
compressive strength value, 53.67 N/mm2 · This finding was supported by microstructure analysis to examine the pores, interfacial bonding, present of void and particle distribution that
lead sample failure. The addition of grog in local clay not only can reduce the shrinkage but also improve the physical and mechanical properties of ceramic bodies. On the other hand, it
also can benefit the waste and reduce the raw material cost if grog and local clay can be utilized especially in ceramic manufacturing. |
