Product Detail

Overview

High recycled-content cements for insitu concrete applications. Contains supplementary cemetitious materials (SCM) made from post industrial waste from steel manufacture and coal-fired electricity generation.

 

 

 

 

 

 

 

BFS (Boral Formwork & Scaffolding) typically contributes to the structural strength of the finished concrete. Applications (normally 60MPA and below) may contain 15-20% of a combination of BFS and flyash (or just flyash) as a default. This has been industry practice for many years.

Recent experience has demonstrated that much higher quantities of SCM (Supplementary Cementitius Materials) may be substituted into concrete mixes. On the 60 Leicester St ' Green Building' up to 60% SCM displaced virgin cement in the insitu concrete without adversely affecting stripping time or developed strength.

It has been demonstrated that the embodied energy of a slab can be reduced by over 50% by partial substitution of cement with SCM combined with the use of recycled steel reinforcement.

For optimal environmental outcome and further reductions to embodied energy consideration should also be given, where available, to the use of recycled aggregate.

The product is available in a number of states - refer to website for details.
