the production of lightweight aggregates (LWAs) by mixing the raw material with 2–5% sawdust. The mixtures were pelletized, dried at 100 jC and burnt to 1100 jC. The laboratory LWA had strength and density similar to commercial LWAs originating from Germany and Denmark. The porosity of their mantle was lower than that of the inner part. Pores

Synthetic Aggregates: Their Role in the Production of Smart

lightweight conductive aggregates (CA) loaded with modified agar gel and where their influence on the resistivity of conductive cement-based materials was evaluated. Results indicate that by impregnation treatment, agar gel was efficiently loaded in porous lightweight aggregates, thus CA with a resistivity of 0.5Ω·m was obtained.


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).
