The effect of calcination conditions on the physical properties of calcines produced from natural Turkish limestones and dolomites was investigated. Calcination experiments were conducted in a tube furnace at temperatures of 1073,1123,1173,1273, and 1373 K, Two different gaseous atmospheres were employed, namely, dry air (100 vol%) and a mixture consulting of CO2 (15 vol%%) and dry air (85 vol%).The physical properties,which involve bulk density (g/cm3),total pore volume (cm3/g), and the pore size distribution of the calcines prepared under different conditions, weredetermined using a mercury porosimeter, It was found that the physical properties of calcines were dramatically affected by the calcination conditions. At high calcination temperatures, because of sintering and shrinking effects, a decrease in porosity, an increasein bulk density and average pore radius were observed, in addition, the calcines prepared in a mixed atmosphere of dry air and carbon dioxide had larger pore sizes than those of calcines prepared in an atmosphere of dry air. © 1995 Taylor and Francis Group, LLC.
