Characterization and Properties of Lampang Kaolinite Clay for Standard Clay

Abstract:

The aim of this study was to study and characterize the properties of raw material for standard clay, Lampang province. The raw materials used in the study are from local sources. They are Lampang kaolin clay (WC-1) and Lampang kaolin residual (WC-2). The characterization of raw material was analyzed by particle analyzer, X-ray fluorescence (XRF) and X-ray diffraction (XRD). The mixing ratio of standard clay as an addition Lampang kaolin clay 50-90% and Lampang kaolin residual 10-50% on physical-mechanical properties of standard clay. The properties of standard clay after firing at temperature at 1200°C were studied. The shrinkage, water absorption and bending strength of standard clay were tested. The results showed that the chemical components of 60%lampang kaolinite clay and 40% Lampang kaolin residual included of large amount of 67.47wt% Silicon oxide and 20.92wt%Aluminum oxide. The physical properties of standard clay had a shrinkage of 11.2%, water absorption of 1.9 % and bending strength of 659 kg/cm2. The standard clay produced fulfilled the requirements of Thai industrial standard (TIS 485-2542).
