Engineered Biochar as Construction Material

Biochar has a broad array of applications and is deployed in a variety of fields, including agriculture, sustainable development, and geoengineering. Various engineering methods have recently been developed and used to widen the application of biochar. One of them is the use of engineered biochar as a construction material. It can be exploited as a material for construction due to properties such as chemical stability, flammability, and low thermal conductivity. This chapter provides an overview of the properties of engineered biochar that make it suitable for the role of construction material. Factors such as pyrolysis conditions specifically, pyrolysis temperature, heating rate as well as pressure, along with various construction material properties have been depicted here. This chapter also highlights the implications of engineered biochar on the physical, mechanical, and durability aspects of building materials. Comprehensively, this engineered biochar is being used as a construction material due to a number of unique and interesting qualities, including the capability to build in a carbon-negative manner in addition to its applicability as an insulating material, biochar-based clay and lime plasters, building bricks, concrete and roof tiles. The chapter also aims to examine engineered biochar's current and future implications in the construction field.
