Foreign bodies and non-clay lumps were removed. The clay sample was soaked in water and impurities were removed. Finally, thermal conductivities and bulk densities of the samples were computed following an established standard.įield survey, sample collection (Kaolinite Clay, Sawdust and Iron Filings), preparation (admixtures, firing, thermocouple and thermometer measurements) and laboratory analysis Thermocouple and thermometer were used to acquire the temperature during the firing of the bricks. The data were acquired, processed and presented. The experimental data on the thermal characteristics and refractory properties of the clay sample were then acquired. These samples were fired in a local kiln that achieved temperature of 900 ☌ - 1200 ☌ to burn-off the sawdust consequently creating pores/cavities where the sawdust had been burnt and to fuse the iron particles with the clay material. The blended ratio of sawdust and iron fillings ranges from 0%, 5%, 10%, 20%, 30%–40%. Thermal analysis of the clay samples was carried out at different ratios of sawdust and iron filings blended with the clay samples. This was done by blending various samples of kaolinite clay with varying percentages of sawdust and iron filings. In this dataset, the influence of admixture of sawdust and iron filings on the kaolinite clay was experimented.
