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.

Lightweight Aggregates: How Do You Make the Right …

The use of lightweight aggregates may have an impact on the compressive strength of the concrete. Highly absorptive lightweight aggregate should be wetted at least 24 hours prior to use. It is not recommended that dry lightweight aggregate be directly batched and mixed because the aggregate particles can continue to absorb water from the mix.

Lightweight Aggregate Concrete | ScienceDirect

Lightweight aggregate concrete differs from the normal weight concrete because of its porous nature and lower strength. This fact is reflected on most of the properties; for example, on physical and mechanical behaviors. Normally all concrete types are designed according to what concrete is sought.
