Could AusPozz™’s Validation Disrupt Traditional Cement Markets and Construction Costs?

Independent Validation of AusPozz™ Performance

Zeotech Limited (ASX – ZEO) has taken a significant step forward in establishing its proprietary supplementary cementitious material, AusPozz™, as a credible and high-performance solution for the concrete industry. An independent peer review conducted by BG&E Pty Ltd, a respected engineering consultancy, has confirmed that AusPozz™ consistently enhances concrete strength and durability across a variety of mix designs.

The review, which analysed concrete mix trials over a 12-month period, found that mixes incorporating AusPozz™ achieved strength improvements exceeding 130% compared to control mixes. This level of performance gain is notable in an industry where incremental improvements can translate into substantial structural and economic benefits.

Technical Advantages Beyond Strength

Beyond strength, the trials demonstrated a 30% reduction in drying shrinkage after 56 days, indicating improved dimensional stability and reduced risk of cracking. This is a critical factor for infrastructure longevity and maintenance costs. Additionally, AusPozz™ effectively mitigates Alkali-Silica Reaction (ASR), a common cause of concrete degradation, by transitioning reactive materials to non-reactive status at a 25% cement replacement level.

Thermal performance was also enhanced, with AusPozz™ reducing peak concrete temperatures during curing, which can lower the risk of thermal cracking and associated failures. The material’s workability and plastic properties were consistent with other supplementary cementitious materials, supporting its practical adoption in commercial concrete production.

Industry Standards and Market Implications

Importantly, BG&E’s review supports AusPozz™’s classification under the Australian standard AS 3852.4 – 2022 for manufactured pozzolans, providing a regulatory and technical foundation for broader industry acceptance. Zeotech’s CEO, James Marsh, highlighted the dual benefits of decarbonising concrete production while delivering superior technical outcomes, positioning AusPozz™ as a compelling option for sustainable construction.

Another key advantage is AusPozz™’s potential to replace silica fume, a costly and difficult-to-handle additive in high-strength concrete. This substitution could yield significant cost and productivity savings, further enhancing AusPozz™’s commercial appeal.

Next Steps and Industry Adoption

Zeotech plans to expand its testing program to include additional durability assessments and a wider range of concrete mix designs, including high-performance concretes. The company is also actively working with Queensland Transport and Main Roads to secure AusPozz™’s inclusion on its approved products list, a critical milestone for market penetration in infrastructure projects.

With sustainability and performance increasingly driving material selection in construction, AusPozz™’s independent validation could accelerate its adoption and support Zeotech’s growth ambitions in the low-carbon materials sector.
