Biochar-Based Cement and Concrete for Sustainable Construction by Tsang, Daniel C.W.; Zhu, Xiaohong;

Long description:

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.

• Focuses on biochar for construction, spotlighting its utilization as a promising investment to contribute to sustainable development
• Covers macro and micro properties of biochar to demonstrate that not only can it serve as a filler but also as a functionalized additive
• Illustrates state-of-the-art application achievements of biochar-based cementitious materials and concrete
