In response to the urgent need for achieving carbon neutrality in the construction industry, with Biochar-Based Cement and Concrete for Sustainable Construction, an international group of experts has set out to provide a timely, comprehensive overview of biochar-enhanced cementitious materials. Although the method is relatively new, extensive research has been conducted in recent years to systematically gather information proving biochar as an ideal medium for carbon sequestration when used as an engineered additive in cementitious materials, but also to strengthen concrete in many key dimensions via enhancements to hydration and integration into the hardened matrix.
The volume stands out as an invaluable resource that offers up-to-date guidance on eco-efficient construction materials’ manufacturing and practical application examples backed by considerations regarding their environmental soundness. At the same time, it stimulates research into future developments with relevance to interdisciplinary audiences both in academia and industry.
