Integrated Gasification Combined Cycle (IGCC) is an eco-friendly power generation technology that produces electricity by gasifying coal at high temperature and high pressure. Coal gasification combined cycle power generation of electricity by converting coal into syngas composed mainly of hydrogen and carbon monoxide and driving the gas turbine using the converted syngas, and converts the heat of the exhaust gas generated during the process of converting to syngas. To generate electricity by turning a steam turbine. The coal gasification combined cycle power generation has a high power generation efficiency, and is an environmentally friendly technology that can reduce environmental pollutants.

The molten slag is generated during the operation of the coal gasification combined cycle power generation, and the geopolymer block may be manufactured by recycling the molten slag.

The preparation of such a geopolymer block requires curing for 24 hours at a temperature of 70 ° C. in the process of converting the geopolymer. At this time, bubbles may occur up to about 40 minutes at the time of conversion of the geopolymer. In the conversion of the geopolymer block, finely divided slag, alkali activator (NaOH, KOH, etc.) and silicon powder (foaming agent) and the like are reacted, and bubbles may be generated in this process.

Conventionally, as described above, the blocks are manufactured in a state in which the generated bubbles are not uniformly distributed, and there is a problem that the thermal insulation and durability of the produced blocks are poor.
