Demolition of the cooling towers of a power station, Athlone, Cape Town, South Africa, 2010. Building demolition and natural disasters such as earthquakes often release a large amount of concrete dust into the local atmosphere. Concrete dust was concluded to be the major source of dangerous air pollution following the Great Hanshin earthquake. [5]
For many years, lead cell batteries were destroyed there and the lead was extracted, leaving the untreated cases on site. An environmental assessment showed that the site was contaminated due to the presence of heavy metals, lead and hydrocarbon pollution. Cement based S/S was employed to successfully remediate 600 tonnes of contaminated soil. [10]

Even so, air pollutants are causing a variety of health and environmental problems. These pollutants are a threat to the population of Africa and the environment they try so hard to sustain. [31] In 2019, air pollution killed 1.1 million people across Africa, according to a study published in The Lancet Planetary Health in October 2021. [32]
The presence of water is always an aggravating factor. Concrete structures immersed in water as dams and bridge piles are therefore particularly sensitive. These reactions are also characterized by slow reaction kinetics, depending on environmental conditions such as temperature and relative humidity. They develop at a slow rate and may take ...
