Summary: The project aims to advance sustainable concrete construction in two ways by establishing a framework for the use of optimum low carbon concrete (LCC) complying to existing TfNSW specifications, and evaluate the viability of new and innovative low carbon concrete systems into the framework. TfNSW would be able to achieve its drive to sustainable construction by expanding its concrete specification to promote the use of concrete with optimum embodied carbon. This can be achieved without any change to the existing design service life specifications. There are 3 key properties which are vital to the long-term performance of concrete structures. They are (1) workability, (2) mechanical and volume stability properties, and (3) design service life durability properties. Concrete can be designed in various ways, using a range of materials with very different embodied carbon, to meet these requirements. The use of optimum low carbon concrete can be simply achieved by an additional requirement of low embodied carbon in TfNSW specifications.
