pUsing plant material as raw materials for construction is arelatively recent and original topic of research. This bookpresents an overview of the current knowledge on the materialproperties and environmental impact of construction materials madefrom plant particles, which are renewable, recyclable and easilyavailable. It focuses on particles and as well on fibers issuedfrom hemp plant, as well as discussing hemp concretes. The bookbegins by setting the environmental, economic and social context ofagro-concretes, before discussing the nature of plant-basedaggregates and binders. The formulation, implementation andmechanical behavior of such building materials are the subject ofthe following chapters. The focus is then put upon the hygrothermalbehavior and acoustical properties of hempcrete, followed by theuse of plant-based concretes in structures. The book concludes withthe study of life-cycle analysis LCA of the environmentalcharacteristics of a banked hempcrete wall on a woodenskele
