Lightweight Aggregate (LWA)
Lightweight Aggregate (LWA) Minergy's LWA production facility was constructed as a means to beneficially reuse coal combustion fly ash from a power plant located in Oak Creek, Wis. LWA was commercially produced between 1994 and 2000, at which time the properties of the fly ash changed as a result of a new source of coal, thus allowing the fly ...

Pozzolanic reactivity of lightweight aggregates
This is demonstrated in Figure 3. The pozzolanic reactivity of a lightweight aggregate based on sintered fly ash such as Lytag also depends on both reactivity of the fly ash and temperature level and duration of the sintering. The firing temperature of lightweight aggregates, which is typically 1200°C, may cause recrystallization, thus ...
