ENVISIA® is a superior lower carbon concrete with excellent performance benefits, along with plastic placement and finishing properties similar to that of conventional concretes.
Showcasing Boral's innovation and proprietary ZEP technology, the ENVISIA® mix is Boral's lowest carbon concrete, providing good early-age strength, superior durability and excellent drying shrinkage properties that make the concrete less prone to cracking.
ENVISIA® is well suited to applications where early strength performance of concrete is of paramount importance, for example, suspended commercial slabs or high-rise construction projects.
Features & Benefits
The lower carbon composition of ENVISIA® is achieved through the use of Boral's proprietary ZEP® technology. ENVISIA® achieves a Portland cement reduction of up to 65% using the Green Star MAT-4 method^ without experiencing the traditional trade-offs in concrete performance.
Due to the inherent properties of the ZEP® technology, ENVISIA® out-performs conventional1 concretes in drying shrinkage and creep - providing up to 50% reduction in shrinkage compared to conventional1 concrete with similar strength characteristics and modulus of elasticity.
ENVISIA® performance as a lower carbon concrete is achieved without compromising the strength or stressing cycle times of the concrete (compared to an equivalent conventional1 concrete).
ENVISIA® provides lower chloride diffusion, water absorption and permeability, compared to an equivalent grade of conventional1 concrete.
ENVISIA® demonstrates plastic, placement and finishing properties that are consistent with conventional1 concrete.
Boral's range of lower carbon concrete is compliant with Australian Standard AS 1379, manufactured from cement that complies with Australian Standard AS 3972.
^Using ENVISIA® can help achieve maximum points from the revised Green Star ‘Concrete’ credit - MAT-4. Please note that individual products are not reviewed or certified under the system. Green Star rating Green Star credit requirements cover the performance of materials in aggregate, not the performance of individual products or brands. www.gbca.org.au/green-star
