Demonstration Slabs

Edmondson Park North Commuter Carpark

After the 1st commercial pour in October 2022, another significant milestone was achieved with the

successful pour of CO2 Concrete on 31 October 2023 by Holcim at a live AW Edwards construction site in

Sydney, Australia. Representatives from Liverpool City Council, Western Sydney University, Holcim, A W

Edwards, and Transport for NSW were present at the pour of this groundbreaking concrete in a 1-meter by 25-meter section of the pathway at Edmondson Park North Commuter Carpark.


It is elevating the bar and achieving an impressive 50 per cent CO2 recycled content ratio, surpassing the

previous maximum of 40 per cent in earlier trials. Once laid, the CO2 Concrete transforms the pathway into a

carbon store, improving environmental outcomes and reducing landfill space by repurposing construction

waste into construction material.

Blacktown Animal Rehoming Centre

The first CO2 Concrete pour was on the 26th of October 2022 at a live A W Edwards construction site in

Sydney, Australia. The slab measured 27m x 2m and is located at the newly built Animal Rehoming Centre in

Blacktown. The slab contains carbon-treated recycled aggregate created via a newly invented carbonation

process. The concrete used for the slab was batched at the Rooty Hill Holcim Concrete Plant as part of the

global Holcim Accelerator Program. The CO2 Concrete team enjoyed great success on the day and received positive feedback from the construction crew on how easy CO2 Concrete was to work with and pour.


Western Sydney University Hawkesbury Farm's CO2 Concrete Slabs

The CO2 Concrete slabs were cast in March 2019 using CO2 Concrete at Hawkesbury Farm at Western Sydney University. The platforms measure 3m x 2.6m and are created using 2 innovative mix designs to support gross animal weight of approximately 1 tonne each for troughs (drinking stations).


Western Sydney University Hawkesbury Farm's Biosecurity Platforms

Western Sydney University Hawksbury Farm has been known for its state-of-the-art agricultural research. Two CO2 Concrete biosecurity platforms in April 2018, were employed for boot cleaning, minimising pests and diseases.
