size aggregate, and excessive fine aggregate are frequently used because the high degree of flowability means less work in placing. At the other extreme, it is inadvisable to use mixtures that are too stiff for conditions of consolidation. They will require great consolidation effort and even then may not be ade-quately consolidated.
Lightweight aggregates | Aggregate Industries
Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.
