Lytag Aggregate
Application

  • Is approximately half the weight of natural aggregate and can replace natural aggregates in many construction applications.
  • Using LYTAG LWA in concrete, both precast and in situ, can reduce the dead weight by over 30%, allowing savings to be made in foundations and steel reinforcement, while still retaining the required structural performance. See Lytag Lightweight Concrete
  • Due to its rounded nature LYTAG LWA is ideal for drainage applications, the excellent hydraulic conductivity makes for quick removal of water, however the high absorption allows retained moisture to return to the ground during dryer spells. See Lytag Sportag and Hortag.
  • It does not cause damage to the plastic pipes.
  • It is also used for bulk fill, arrestor beds, refractory concrete and filter media.

DOP certificate (CE mark) available on request.

ISO 9001, 14001 and 18001 certificates, BES 6001 certificate (excellent rating).

Description

LYTAG lightweight aggregate (LWA) is specifically designed and manufactured to meet the requirements of modern construction practice. The raw material is pulverized fuel ash (pfa), the waste produced in coal-fired power stations. The aggregate formed is ‘sintered pulverized fuel ash lightweight aggregate’, more commonly known as LYTAG lightweight aggregate.

LYTAG LWA is manufactured by pelletizing the ash. The pellets are then heated on a sinter strand to a temperature of around 1100°C. The result is a hard, honeycombed structure of interconnecting voids within the aggregate. The pellets formed are rounded in shape and range in size from 14 mm down to fines, these are processed to the required grading, depending on the final use.
