Biochar in concrete
When added to concrete mixtures, biochar reduces cement demand and lowers the construction carbon footprint – without compromising structural performance.
The construction industry has entered a new phase and sustainable materials like biochar have become key to meeting corporate and project level targets. Engineers, researchers, and material developers are evaluating how biochar performs within established mix designs but also as an ingredient in high performance products.
In concrete, biochar is mainly used either as a supplementary cementitious material (SCM) or as a filler as a partial replacement for sand. Its particle characteristics can influence density, strength development, curing, and durability, depending on dosage and mix design.
Biochar’s carbon sequestration properties can also support project sustainability goals and contribute to certain credits within certification systems such as LEED or broader ESG alignment.
