A method of producing sulfur concrete using precipitated salts. The method comprises obtaining precipitated salts from a salt solution, which comprises: mixing the salt solution with calcium oxide to form a basic suspension; treating the basic suspension using carbon dioxide to cause salts to precipitate from the salt solution; and separating the precipitated salts out from the treated basic suspension to produce a treated salt solution. The method also comprises forming the sulfur concrete, which comprises mixing elemental sulfur with a modifying agent to form a sulfur-containing polymer; pre-heating aggregates comprising at least the precipitated salts; and mixing the aggregates with the sulfur-containing polymer to form the sulfur concrete.
