|Title:||Characterization and properties of lampang kaolinite clay for standard clay|
|Abstract:||© 2019 Trans Tech Publications, Switzerland. The aim of this study was to study and characterize the properties of the raw materials for standard clay in Lampang province. The raw materials used in the study were from local sources comprising Lampang kaolin clay (WC-1) and Lampang pottery stone (WC-2). The characterization of the raw materials was analyzed by a particle analyzer, X-ray fluorescence (XRF) and X-ray diffraction (XRD). The mixing ratio of the standard clay was an addition to the Lampang kaolin clay of 50-90% and Lampang pottery stone of 10-50% on the physical-mechanical properties of the standard clay. The properties of the standard clay after firing at a temperature of 1,200°C were studied, and the shrinkage, water absorption, and bending strength of the standard clay were also tested. The results showed that the chemical components of 60% of the Lampang kaolinite clay and 40% of the Lampang pottery stone included a large amount of silicon oxide (67.47wt%) and aluminum oxide (20.92wt%). The physical properties of the standard clay had a shrinkage of 11.2%, water absorption of 1.9%, and bending strength of 659 kg/cm2. The standard clay fulfilled the requirements of the Thai industrial standard (TIS 485-2542).|
