Calcium carbonate (CaCO3) is a chemical compound known for its applications as a fire-retardant agent because it delays fire expansion and reduce the fire load of a burning material (Hirschler, 2014). Mussel shells are mainly composed of calcium carbonate, which is a known substance that releases carbon dioxide into the surrounding air
