Strong durable material can be made at low temperature.

#ARCTIC. #SIBERIA. THIS IS TAIMYR. Researchers at the research and educational center Russian Arctic proposed to produce a sulfur composite material for construction from technical sulfur, which accumulates in large quantities in deposits in the Arctic regions of Russia. Due to remoteness, waste is stored and not taken out.

Other man-made waste from the mining industry can be added to molten sulfur: fine fractions of sand, crushed stone, ash – what is usually thrown away. The result is sulfur concrete. If you add asphalt components, you get gray asphalt.

After hardening, a sufficiently durable material is obtained. In order for the structures to be durable, additives are needed – modifiers. They can be waste wood processing. The result is a new material that is promising for use in the Arctic.

“Sulfur is a thermoplastic material. It’s heated, a modifier is added to the melt, and the fillers are the same as in cement: sand, crushed stone, but not in an aqueous solution, but in a sulfur melt”, scientists explained.

All these processes can be carried out at negative temperatures, which is important for high latitudes.
