The market for limestone is remarkably consistent. Quarried limestone can be used to neutralize acidity, so it can be added to soils or lakes. Limestone is used in the iron manufacturing industry, is required for cement, concrete, and mortar mixes, and is heated with sand and sodium carbonate to create glass. 3. It is extremely affordable.
