Chemical properties of coal. Coal comes in four main types or ranks: lignite or brown coal, bituminous coal or black coal, anthracite and graphite.Each type of coal has a certain set of physical parameters which are mostly controlled by moisture, volatile content (in terms of aliphatic or aromatic hydrocarbons) and carbon content.. Moisture. Moisture is an important property of coal, as all ...
5.6.2. exemption of material consisting wholly or mainly of, or being part of anything consisting of coal, lignite, slate or shale (section 17(4)(a)) in so far as the exempted material consist wholly of coal, lignite, shale, slate that is used as aggregate or consist mainly of coal, lignite, shale and slate

Test for Undesirable Lightweight Material.— Soft, laminated pieces of aggregate, such as chert or shale, are harmful to concrete. Coal and lignite, also, are harmful and are distinguished from the lightweight materials by the brownish black or black color of the particles. Visual examination of the coarse aggregate will often show these minerals.
