The manufacturing of building materials can be energy intensive and produces high greenhouse gas emissions, incentivising the sector to explore new methods for developing low-carbon or even net-zero products to ensure climate goals can be met alongside economic development.
Research has shown that biochar could be an important part of the solution, through its application in Concrete, Asphalt, Cement, and other building materials.
Biochar is carbon negative in its production, with research showing that not only can it replace less sustainable aggregate materials, it can also add valuable properties that deliver desirable properties in the product, as well as helping the environment.
How can biochar improve concrete?
The latest research into biochar's applications within concrete is very promising, showing the potential to deliver significant benefits for developers and the environment.
Incorporating biochar into concrete may help to improve:
- Compressive strength and durability
- Provide resistance to cracking
- Enhance acoustic performance
- Provide better moisture insulation
- Reduce the overall carbon footprint of the build
How can biochar improve asphalt?
The incorporation of biochar into asphalt materials can potentially improve their rheological, mechanical, and durability properties, whilst also reducing their environmental footprint. Biochar can be used as an asphalt binder modifier to enhance multiple structural properties:
Incorporating biochar into concrete may help to improve:
- Enhanced rheological properties
- Improved ageing resistance and durability
- Improved temperature sensitivity
- Increased rutting resistance
- Enhanced cracking resistance
- Improved moisture resistance
- Reduced environmental impact
How can biochar improve cement?
The latest research into biochar's applications within cement is developing at pace and is showing many potential environmental and structural benefits for the sector:
- Increased compressive strength
- Increased tensile strength
- Improved sound absorption
- Enhanced fracture resistance
- Reduced carbon footprint
