The use of pozzolanic volcanic ash as a super-binding additive in concrete-mixing process has been known for over two millennia, as evidenced by countless Roman structures that still stand today.
In a world increasingly committed to reduction of carbon emissions, the construction industry is actively seeking solutions to make the built environment more sustainable. 'Greening concrete' and the decarbonisation of concrete has emerged as a major goal.
Concrete manufacturing is estimated to contribute up to 8% of global annual CO₂ emissions. UPSA's PSA resource can replace approximately 40% of the cement in concrete production leading to significant carbon emissions savings. This enables governments and developers to construct strong, durable structures, deploying PSA, designed to last for centuries rather than decades, with the additional benefit of carbon credits once accredited and verified by a designated agency. UPSA will market its PSA resource to clients for sustainably constructing, designing, building, and operating projects to minimise environmental impacts while maximising long-term structural benefits.
