The geopolymer technique may be a future-oriented technology for saving energies and resources. This technique requires 3 fundamental elements so-called filler, hardener and geopolymer liquor being generally an alkaline silicate solution. Quartz powder, water quenched granulated blast furnace slag and sodium silicate solution prepared from $Na_2O\cdot2SiO_2$were chosen for these three elements. After mixing these starting materials in appropriate proportions, monoliths were prepared by casting at room temperature. Strength tests showed the following results for 28d age speciment: 7.9-12.7 MPa in flexural strength and 20.2-32.8 MPa in compressive strength, depending on geopolymer liquor/solid ratio, P/S and fineness of the quartz powders used.

The large amount of energy is consumed in a process for keeping the high temperature melting pool. For this reason, in addition to the wastes input to keep the high temperature melting pool, it is necessary for an auxiliary fuel and LOx to throw into the melting pool. So in this study, using a new melting furnace system, the experiments to keep the melting pool with minimal energy without throwing an auxiliary fuel and LOx was carried out. Also it is hoped that the results of the experiment will be available to analyze keeping a melting pool and behavior in a melting furnace.
