Credits within the MATERIALS category

Materials: RAAF BaseRichmond, NSW

The Aim of the Credit is:

To reduce embodied energy and resource depletion due to use of concrete

‘The Concrete Credit’

Up to three points are awarded for ‘significant recycled content’; that is made up of . . .

- Two points awarded where the average quantity of Portland cement has been substantially reduced as a result of substitution with industrial waste products:

• 1 point = 30% for in-situ concrete, 20% for pre-cast concrete and 15% for stressed concrete; and

• 2 points = 60% for in-situ concrete, 40% for pre-cast concrete and 30% for stressed concrete;

- An additional point awarded where 20% of all aggregate used for structural purposes is recycled (Class 1 RCA) or slag aggregate AND no natural aggregates are used in non-structural uses
