Abstract
This study reviewed the usability of sludge, a material that is additionally created when polysilicon (a solar light material) is produced, as the raw material for cement clinker. It was evaluated that when cement clinker is produced, the chloric component of polysilicon acted as a mineralizer in the firing process. In addition, the physical features of the produced cement were measured. The setting time of the produced cement was reduced as the amount of content of polysilicon sludge increased. Such results were drawn because the chloric component acted as hydration accelerator and enhanced the dissolution of calcium hydroxide that was formed by hydration of $C_3S$. Furthermore, for such reason, on the day 1, the compression strength of mortar increased as the content of polysilicon sludge increased. In day 3, 7, and 28, the tendency in which the compression strength increasing up to 5% of the amount of added polysilicon sludge was shown. It is because when clinker was produced, the chloric component increased the amount of $C_3S$ mineral created, thus enhancing the compression strength after day 3.
