"One of the most significant changes to Australian cement technology and resulting innovation in concrete in the past 40 years."
~ Tony Thomas, Chief Engineer, Boral Concrete
ENVISIA® was designed from the outset to reduce the carbon emissions associated with concrete production. Cement manufacture is a key carbon-emitting step in concrete production, so less cement can mean lower levels of embedded carbon in concrete.
ENVISIA® is a lower carbon concrete with excellent performance benefits and plastic placement and finishing properties similar to conventional concretes.
ENVISIA® allows less cement to be used in the concrete manufacturing process without impacting on performance.
ENVISIA® achieves early age strength equivalent to conventional concrete (post tensioned and precast) despite 50 per cent cement replacement.
It outperforms conventional concretes in shrinkages and creep, providing up to 50 per cent reduction in shrinkage compared to conventional concrete.
Boral's General Manager – Innovation Development, Dr Louise Keyte, has more than 20 years’ experience in research and development for the construction industry and has been working for Boral for the past 10 years. Her interests include developing other value-added concretes. Together with former Boral General Manager – Innovation, Redmond Lloyd, she developed ENVISIA® concrete and is the inventor on several patents in Australia and the United States.
Dr Keyte leads the Innovation Factory in Australia, which develops new products and is one of the cornerstones of Boral's vision of achieving performance excellence through innovation. The Innovation Factory's focus is to make it more systematic, strategic and focused on Boral's needs and, ideally, making the process more efficient. Redmond has been involved in research and development in cement and concrete for years.
She is also passionate about encouraging diversity in the construction industry and a former member of Boral's Diversity Council. Prior to joining Boral, Louise was involved in the manufacture of low-carbon masonry units in China and design of low-carbon light-weight panels with the University of Christchurch.
Her practical experience is reinforced by a strong theoretical background:
PhD at University of Melbourne – research was motivated by the need to understand the reaction mechanisms of supplementary cementitious materials including slag and fly ash to better design low-carbon binders Two current Australian Research Council grants with the University of NSW to further cement research
