Method of producing sulfur concrete using carbonated salts

A method of producing sulfur concrete using precipitated carbonated brine salts, the method comprising:

• obtaining precipitated brine salts from a brine salt solution, wherein obtaining the precipitated brine salts comprises:
• mixing the brine salt solution with calcium oxide, wherein the calcium oxide is comprised in carbide lime waste, to form a basic suspension having at least the calcium oxide and the brine salt solution as constituents;
• treating the basic suspension using carbon dioxide so that at least a portion of the carbon dioxide reacts with the constituents to cause carbonated brine salts to precipitate from the salt solution;
• and
• separating the precipitated carbonated brine salts out from the treated basic suspension to produce a treated brine salt solution;
• and
• forming the sulfur concrete, wherein forming the sulfur concrete comprises:
• mixing elemental sulfur with a modifying agent to form a sulfur-containing polymer;
• pre-heating aggregates to a pre-determined temperature, wherein the aggregates comprise at least the precipitated carbonated brine salts and solid carbide lime waste;
• and
• mixing the aggregates with the sulfur-containing polymer to form the sulfur concrete,
• wherein:
• the precipitated carbonated brine salts and/or solid carbide lime waste are present in a total amount of 29 wt. % to 34 wt. % of the sulfur concrete, and
• the sulfur-containing polymer is present in an amount of 33 wt. % to 38 wt. % of the sulfur concrete.
