Manufacturing technology of products based on wastes from the process of mining, and the processing of nonferrous metals and waste sulphur. The innovativeness of the process is related to the method of liquid waste sulphur polymerisation using post-flotation wastes and in its application as bonding for the production of sulphur concrete.
Ready concrete mass is formed into products applied in road, railroad, hydro-technical infrastructure and in construction. The possibility of granulating the sulphur concrete in order to transport it as a packed semi-finished product for large distances and execution of construction elements directly at a site represent global innovation. It provides new applications for sulphur concretes that have been unavailable until now.
