LIGHTWEIGHT AGGREGATES IN THE UK. Whilst lightweight aggregates have been used for many years, the development of high quality manufactured lightweight aggregates has been slow due in no small part to the attitude of the producers of the industrial wastes which form the raw materials for much of the modern lightweight aggregate production.

Expanded shale, expanded clay and expanded slate (ESCS) lightweight aggregate is prepared by expanding select minerals in a rotary kiln at temperatures over 1000° C. The production and raw material selection processes are strictly controlled to ensure a uniform, high quality lightweight aggregate.


Lightweight aggregates are defined as natural or artificial materials, which are granular, porous and light in weight. They are categorized as normal LWA, ultra LWA and heavy LWA. The natural materials most frequently used for their production are clay (vermiculite, smectite, montmorillonite) and sedimentary rocks (slates, shales).
