ENVISIA® Lower Carbon Concrete

New, ENVISIA® Lower Carbon Concrete Mix Design
BREAKTHROUGH TECHNOLOGY IN CONCRETE MIX DESIGN
ENVISIA® is a lower carbon concrete with excellent performance benefits and plastic, placement and finishing properties similar to conventional² concretes.

ENVISIA® uses Boral's proprietary ZEP® technology, which allows less cement to be used in the concrete manufacturing process without impacting on performance.

The result is ENVISIA® concrete with lower levels of embedded carbon¹ and concrete shrinkage and creep properties³ that can outperform conventional² concrete of similar characteristic strength and modulus of elasticity.

SUSTAINABILITY ADVANTAGE
The lower carbon composition of ENVISIA® is achieved using ZEP®, Boral's proprietary cement activating agent. ENVISIA® achieves a Portland cement reduction of up to 65% using the Green Star MAT-4 method² without the traditional trade-offs in concrete performance.
(See Graph 1 for comparative performance)
+ EARLY STRENGTH
ENVISIA® performance as a lower carbon concrete is achieved without compromising concrete strength or stressing cycle times compared to the same grade of conventional¹ concrete.
+ CONSISTENT BEHAVIOUR
ENVISIA® demonstrates plastic, placement and finishing properties that are consistent with conventional¹ concrete.
NOTE: Available in NSW ONLY
+ LOW-SHRINK ADVANTAGE
Due to inherent properties in the ZEP® technology, ENVISIA® outperforms conventional¹ concretes in shrinkage and creep – providing up to 50% reduction in shrinkage compared to conventional¹ concrete.
(See Graphs 2 & 3 for comparative performance)
+ High-Durability
ENVISIA® provides lower chloride diffusion, water absorption and permeability, compared to an equivalent grade of conventional¹ concrete.
+ AS1379 COMPLIANT
Our new concrete range is compliant with Australian Standard AS1379 from cement that complies with Australian Standard AS3972.

Disclaimers:

1. Boral Laboratory Testing, March 2013, indicated that the manufacture of ENVISIA® concrete with ZEP® technology resulted in a 27% reduction in embedded carbon levels compared to Boral standard 50 MPa PT concrete.

2. Conventional concrete refers to concrete containing Boral's currently used blends of Portland cement and supplementary cementitious material that do not include ZEP® technology, that has been in common use prior to the availability of ZEP® technology and compliant with AS1379.

3. Boral Laboratory Testing, conducted from August 2012 - June 2013 indicated that ENVISIA® concrete with ZEP® technology provides up to 50% reduction in shrinkage compared to conventional concrete and reduces creep strain by 40% over conventional concrete with no reduction in early strength or impact on cycle times.

4. Boral Test Results indicated that ENVISIA® concrete with ZEP® technology provides lower chloride diffusion (Boral Field Testing 2011) and lower water absorption and permeability (Boral Laboratory Testing (NATA Facilities No. 547 and 9968) Feb/March 2013) when compared to an equivalent grade of conventional¹ concrete.
