A modified sulfur binder capable of implementing a physical property of being re-melted at a temperature less than 100° C., by mixing sulfur with a heterocyclicamine or alkylamine-based modifier and a dicyclopentadiene-based modifier, and a fabrication method thereof. A hydraulic modified sulfur material composition capable of being mixed with water by adding a surfactant to the modified sulfur binder, and obtained by mixing aggregate and a hydraulic material to the modified sulfur binder, and a fabrication method thereof. A hydraulic modified sulfur material obtained by molding the hydraulic modified sulfur material composition, and a fabrication method thereof. A combustible modified sulfur material composition obtained by adding aggregate to the modified sulfur binder, and by selectively adding a filler to the modified sulfur binder, and a fabrication method thereof. A combustible modified sulfur material obtained by molding the combustible modified sulfur material composition, and a fabrication method thereof.
