Abstract: “The main purpose of this study is to investigate the utilization of blast furnace slag (BFS) in the production of briquettes as a replacement of soil (S). To achieve this first, some physical properties of the materials used were determined. Thermal properties of the materials were examined by using differential thermal analysis- thermo gravimetric analysis (DTA-TG). Following the characterization of the materials, the samples of briquettes made with BFS. Its replacement ratios with soil were 0, 2, 5, 10, 20% in mass basis (w/w). The mixtures were prepared and sintered at 900C in the furnace. Compressive strength tests results were presented. It can be said that BFS affected sintering behavior of the briquettes. Compressive strength results of the briquette samples indicated that BFS containing briquettes with 39.4MPa compressive strength (No#2), which was higher than the requirements of Turkish Standard Specification (TS EN 771-1) and it was also higher reference mixture’s (No#1).”
