  1. Limestone and clay are heated to make cement Limestone is also called calcium carbonate When limestone is heated, calcium hydroxide is made. Endothermic reactions take in energy. ü ü û ü Cement is mixed with sand and water to make mortar. Limestone neutralises alkaline soil. Quarrying damages the environment by making lots of dust and noise. Calcium Oxide has the chemical formula CaO. ü û ü ü Limestone is heated with sand and sodium carbonate to make glass. No energy is needed to produce cement and quicklime. Waste materials produce unsightly tips. Slaked lime is an acid. ü û ü û Slaked lime is also known as calcium hydroxide. Limestone can be crushed and used for road surfaces. Limestone is made from plants. When calcium carbonate breaks down, carbon dioxide is made. û ü û ü
