Effects of cigarette butts addition on thermal conductivity and ceramic properties of brick clay
The influence of the addition of cigarette butts, as dangerous waste material, to the properties of the brick clay "Čavka" near Busovača was studied. The cigarette butts were added to the clay in amounts of 5 mass% and 10 mass%. Testing of the samples included testing of consistency, plasticity, Atterberg plastic and liquid limits, drying and firing behavior and refractoriness. Also, apparent density, apparent porosity, water absorption, flexural and compressive strength were investigated on the samples fired at different temperatures. Thermal conductivity was tested on sample fired at 1173 K. Addition of cigarette butts improved insulation characteristics and drying sensitivity, while other properties remain within the required limits for brick industry.
