What is Asbestos?
Asbestos is a generic term for a number of fibrous silicate minerals. There are two major groups of asbestos:
- The most abundant kind of asbestos is the serpentine group, which contains chrysotile (white asbestos); and
- The amphibole group, which contains amosite (brown asbestos), crocidolite (blue asbestos), tremolite, actinolite and anthophyllite.
Asbestos fibres have a very high tensile strength and are known for their resistance to heat, fire, acids, alkalis and corrosion.
