Portland Cement content in concrete compared to GBCA guidelines

Sam4167 February 17, 2020 at 11:49 pm

How does the Portland Cement content in the ‘industry average’ concrete compare to Green Star guidelines (reference case for credit 19B.1.1 portland cement reduction, as defined by AS 1379)?

Concrete Strength Grade(MPa) / Portland Cement Content (kg/m3)
20 / 280
25 / 310
32 / 360
40 / 440
50 / 550
65 / 550
80 / 610
100 / 660

Any comment on this?

Table 34 in this report (Life Cycle Inventory of Cement & Concrete produced in Australia V1.3 – Tim Grant, Life Cycle Strategies 2015) appears to align with the above.
