Building materials for sustainable and ecological environment This book uses theories hypotheses policies practical insights and case studies to introduce and elucidate green building materials for sustainable construction. Cement is the most widely used building material in construction; however it is not sustainable being responsible for 7% of global carbon dioxide emissions and consuming huge quantities of energy. In order to limit the ecological damage sustainable building materials are needed. Ecosystems are a source of important lessons and models for transitioning the built environment onto a sustainable path that opens options for sustainable building material in construction. The book provides a guide for readers seeking knowledge on sustainable building materials with the potential to lower environmental impact by reducing CO2 emission throughout the building’s lifecycle. The book is motivated by recent rapid advances in sustainable building materials production including green building materials made of industrial by products and recycled wastes earth materials plant based materials microbial based materials or supplementary cementitious materials to reduce the environmental impacts of traditional building materials. Discussing the development and applications of various sustainable building materials including related case studies and addressing the environmental issue with a holistic and systematic approach that creates an ecology of construction for sustainability in infrastructures it offers promising solutions to achieve renewable and sustainable building materials for the future.
