Description :

Lightweight aggregate used as a basic construction material and as a component of other materialssuch as concrete, mortar, blocks and screeds.Lytag is manufactured from a by-product of bituminous coal fired power stations. The power station grinds coal into a very fine powder and uses this powder to fire the furnaces. Upon combustion of the coal a fine ash residue is left which takes the form of microscopic spheres. This ash is mixed with water and occasionally other powdered materials such as coal in small quantities and fired using recycled oil.
