Research: Biochar as a Building Material

Sequestering carbon and strengthening concrete

A study from NREL hypothesized that woody biochars-with higher surface area and water sorption capacity can replace cement at higher levels than previously thought giving the potential for carbon negative concrete by 2050.

Conclusion:

  • Biochar can replace up to 32% of cement in concrete
  • Concrete enhanced with biochar is more resistant to wear and tear and shows improved compressive strength and durability.
  • Biochar’s smaller pores, improved flexural strength.
  • Every ton of biochar used captures 2.2 tonnes of CO2-stored long-term in concrete.
  • Biochar in concrete offers cost savings in the long term due to improved material
    properties and reduced need for repairs.
