Low Carbon Solutions for Sustainable Construction
Reduce embedded carbon by 50% per m³ with our low carbon concrete mix – compared to standard CEM1 mix design.
Why we need low carbon concrete
A United Nations report in 2019 estimated that the construction industry is responsible for 38% of all global energy-related CO2 emissions. Carbon dioxide is a key greenhouse gas contributing to global climate change – we need to reduce the amount of carbon we produce to a level that the planet can deal with.
We’re developing environmentally friendly alternatives to cement to reduce the carbon footprint of concrete structures. This contributes to The Environment Agency’s goal to achieve net zero carbon emissions by 2030, as well as the National Grid’s Net Zero by 2050 goal.
Reduce Carbon Increase Durability
Sensicrete will lower the carbon footprint of concrete without affecting its performance or structural design. The new concrete mixes use less cement and steel, resulting in less embodied carbon, and increases the design life of the concrete structure.
Low Carbon Precast Concrete
Lowering carbon is only part of the story
Lowering the amount of carbon in a concrete product or structure is a step in the right direction, but we can still do more to tackle the effects of climate change.
If we look at other nature-based solutions, we can add more value to concrete products.
Frequently Asked Questions
How do you reduce carbon in concrete?
Reducing the quantity of cement can lower concrete’s carbon footprint – we use Ground Granulated Blast-furnace Slag (GGBS) as part of a 50/50 mix. You could also use a self-healing additive to reduce the amount of steel reinforcement needed.
Why is net zero important?
In 2019, parliament passed legislation committing the UK to become a net-zero emitter of greenhouse gas by 2035. CO2 emissions need to fall to stabilise climate change – the longer it takes to do so, the worse the effects of climate change will be. It forms a key part of the Paris Agreement in keeping the global temp. to 1.5 degrees above pre-industrial era levels.
What is embodied carbon?
Any CO2 produced during the manufacturing of building materials (material extraction, transport to manufacturer, manufacturing), the transport of those materials to site, and the construction methods used.
Is concrete a green building material?
Concrete can be considered sustainable due to its:
- Long service life
- Low life-cycle cost
- Safety and reliability
- Ability to be recycled and reused
