Abstract

As a method of utilizing sulfur, which is excessively supplied due to the development of relevant industries, the application of sulfur polymer to roads is drawing attention to consume the excessively supplied sulfur and take full advantage of the properties of sulfur. Sulfur is produced as a byproduct from oil refineries and other relevant industries, and a vicious circle may be formed if the byproduct sulfur is not consumed appropriately and thus has to be discarded. This situation is considered a problem that should be tackled urgently in not only in Korea but also most advanced countries. As a solution to the problem, the application of sulfur polymer as an industrial material is drawing considerable attention. However, the exothermic and high-temperature reactions involved in the sulfur polymer manufacturing process may threaten the safety of the workers, posing an obstacle to the industrial application of sulfur-based materials. These issues have highlighted the limitations of the industrial application of sulfur polymer. Studies have been steadily conducted to resolve the problem, and improved sulfur polymer materials have been developed gradually. In the present study, as an effort to overcome the limitations of the industrial application of sulfur polymer, a sulfur polymer manufactured by a ripening process and nano-sulfur particles prepared by a ultrasonic process were used to manufacture room temperature sulfur polymer asphalt and a nano-sulfur concrete composite to verify the applicability of sulfur polymer as an industrial material.
