Lightweight aggregate is a mineral material used to reduce the density of building blocks.
Expanded clay is one type of lightweight aggregate. It has a porous internal structure and a hard ceramic shell, making it useful for lighter concrete blocks and masonry products.
Expanded clay can reduce block weight, support thermal performance and improve handling. It is stable, mineral and suitable for industrial production when the correct particle size and mix design are used.
Yes, expanded clay can be used in lightweight concrete blocks. Suitability depends on the required strength, density, insulation performance and production method. Technical testing is recommended before full-scale production.
Expanded clay can contribute to better thermal performance because of its porous structure. The final insulation value depends on the block design, mix composition, density and production quality.
Yes. Expanded clay can often be supplied in bulk, big bags or other formats depending on the supplier, volume and logistics requirements.
