Abstract

Gravel is made from a mixture of a spinel and a chemically bonding matrix of refractory calcareous or siliceous binder. Spec. the spinel has a wide range of compsn., but chromite extraction residue is esp. prefd: the binder is chosen from ordinary clay or schist, sodium fluorosilicate, red mud, clinker, olivine or furnace slag (esp. phosphorus slag); 10-90 wt% of the spinel is used. The gravel incorporated with a bitumen, resin or cement, forms an excellent, polish-resistant, high friction surfacing for roads.
