Boral has specially designed Lightweight Concrete using a non-toxic treated polystyrene aggregate or by the use of cellular foam injection by specially trained applicators. Depending on local availability, special lightweight aggregates may also be included in the design for enhanced strength capability. Standard concrete as a density of around 2300kg/m3 and Lightweight concrete generally has densities of less than 2100kg/m3.
Note: availability varies by region so please check with our team whether this product is available locally.

Features & Benefits
- Non-toxic treated polystyrene aggregate
- Lightweight aggregate
Typical Lightweight concrete characteristics:
- Cellular foam injection – 1100-1700 kg/m³ with compressive strengths ranging from 6-15 MPa depending on required densities
- Polystyrene Lightweight concrete – 600-2000 kg/m³ with compressive strengths from 1-25 MPa
- Lightweight aggregate – as low as 1950 kg/m³ with compressive strengths up to 40 MPa (dependent on aggregate availability)
All Boral concrete mixes are designed to comply with AS1379 – Specification and supply of concrete
