As Australia moves toward a more sustainable construction future, Boral is leading the way with its innovative range of low carbon concrete solutions. Designed to meet the growing demand for environmentally responsible building materials, Boral’s products offer a powerful combination of performance, durability, and reduced environmental impact.
What Is Low Carbon Concrete?
Low carbon concrete—also referred to as green concrete, eco concrete, or sustainable concrete—is engineered to significantly reduce the embodied carbon typically associated with traditional concrete. Boral achieves this by replacing a portion of Portland cement with supplementary cementitious materials such as fly ash and ground-granulated blast-furnace slag. These materials are not only industrial by-products but also contribute to improved durability and performance.
Boral’s Low Carbon Concrete Range
Boral offers three distinct low carbon concrete products, each tailored to different project needs:
- ENVIROCRETE®: Ideal for general applications, this product offers a reliable low carbon option where early age strength and shrinkage control are not critical.
- ENVIROCRETE® PLUS: Designed for projects requiring better early strength and drying shrinkage performance, making it suitable for some post-tensioned applications and marine environments.
- ENVISIA®: The flagship product in Boral’s range, ENVISIA® delivers excellent early age strength and minimal drying shrinkage. Its light colour and smooth off-form finish make it a favourite for architectural applications.
All three products are backed by Boral’s proprietary ZEP® technology, which enhances performance while reducing carbon emissions by up to 70% compared to traditional concrete.
Proven Performance in Real-World Projects
Boral’s low carbon concrete has already made a significant impact across Australia. One standout example is the Sydney Metro project, where ENVISIA® was pumped over a kilometre underground to form a durable track slab. This application not only demonstrated the product’s superior pumpability and strength but also its ability to reduce reliance on high-energy cementitious materials.
Another example includes its use in multi-residential and commercial buildings such as Quay Quarter Tower, where developers are increasingly choosing Boral’s eco concrete to meet sustainability targets without compromising on structural integrity or aesthetics.
Why Choose Boral?
With over 168 batching plants offering low carbon concrete across Australia, Boral is uniquely positioned to support projects of all sizes. In fact, 30% of Boral’s concrete sales now come from its sustainable concrete range. The company also holds comprehensive Environmental Product Declarations (EPDs), giving clients confidence in the environmental credentials of every mix.
