| dc.description.abstract | Porcelain tiles have excellent mechanical strength with low porosity (almost zero water absorption), durability, chemical and stain resistance. Due to these excellent properties, porcelain tiles had successfully captured new market segments: floor and wall, adding to the strong demand in building construction. However, porcelain tile is reported to have high thermal conductivity and low solar reflectance which is reduce the thermal comfort and subsequently not suitable for building construction. Therefore, a low thermal conductivity and high solar reflectance porcelain tiles is fabricated to improve its thermal comfort by altering the composition and firing temperature of the porcelain tiles. The aim of this study is to study the effect of different body composition and firing temperature on the properties of porcelain tiles. The new body compositions of porcelain tile powder were milled and compacted at 18 MPa to obtain rectangular shape samples. The compacted samples were fired at 50°C/min up to 1200°C and soaked for 15 minutes before cooling down to room temperature. Among C1, C2 and C3 body composition, C3 show lowest fired shrinkage (7.75%), lowest bulk density (2.30g/cm3) and highest MOR (59.71 MPa) values and at the same time have the lowest thermal conductivity (1.27 W/mk) and highest solar reflectance (80% in near infrared region).Thermal conductivity and solar reflectance is govern by phase formation in which C3 composition reduced by 33% of thermal conductivity and increases of solar reflectance up to 80% (near infrared region) compared with control sample due to the formation of low thermal conductivity phase (cordierite). Since C3 sample shows the optimum properties compared with other samples, the firing temperature of the sample were altered at 1150 °C, 1175 °C and 1225 °C to observe whether it worth to improve the properties of porcelain tiles. Selection of these firing temperature were done by plotting the vitrification curve. It was observed that the thermal conductivity of C3 samples decreases after lowering the firing temperature to 1150°C. The solar reflectance also increases after lowering the firing temperature. Although C3 sample gives low thermal conductivity and higher solar reflectance values, the MOR values obtained from this firing temperature were reduced in comparison with the one fired at 1200°C firing temperature. Also, C3 sample fired at 1150 °C showed the highest water absorption value which is not appropriate for construction application. Thus, it was concluded that the porcelain tiles made using C3 composition and fired at 1200°C are a suitable candidate to fabricate porcelain tiles with good properties (high MOR, low water absorption, low thermal conductivity and high solar reflectance) for building construction. | |
