Cement - Wikipedia
Non-hydraulic cement, such as slaked lime (calcium oxide mixed with water), hardens by carbonation in contact with carbon dioxide, which is present in the air (~ 412 vol. ppm ≃ 0.04 vol. %).First calcium oxide (lime) is produced from calcium carbonate (limestone or chalk) by calcination at temperatures above 825 C (1,517 F) for about 10 hours at atmospheric pressure:

Heavy metals - Wikipedia
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic nuers.The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic nuer, while a chemist would likely be
