Bio-aggregate-based Building Materials (ePub)

Using plant material as raw materials for construction is a
relatively recent and original topic of research. This book
presents an overview of the current knowledge on the material
properties and environmental impact of construction materials made
from plant particles, which are renewable, recyclable and easily
available. It focuses on particles and as well on fibers issued
from hemp plant, as well as discussing hemp concretes. The book
begins by setting the environmental, economic and social context of
agro-concretes, before discussing the nature of plant-based
aggregates and binders. The formulation, implementation and
mechanical behavior of such building materials are the subject of
the following chapters. The focus is then put upon the hygrothermal
behavior and acoustical properties of hempcrete, followed by the
use of plant-based concretes in structures. The book concludes with
the study of life-cycle analysis (LCA) of the environmental
characteristics of a banked hempcrete wall on a wooden
skeleton.
