Calcium carbonate
Calcium carbonate is limestone that has been milled and sized and has various applications, including steelmaking, filler for asphalt mixtures, flue gas desulfurization in power plants, and feed for poultry, pigs, and cattle. Recently, demand for calcium carbonate has also increased to improve the fluidity of ready-mixed concrete (high-fluidity applications). Stable demand is expected to continue in the future.
