This book deals with the fundamental principles underlying the environmental degradation of widely used and economically important construction materials. The invited contributions cover aspects such as the deterioration mechanisms of materials and metal corrosion, environmental pollutants, micro- and macro-climatic factors affecting degradation, the economic impact of damaging processes, and fundamental protection techniques for buildings, industrial and agricultural facilities, monuments, and culturally important objects. Basic details of ISO standards relating to the classification of atmospheric corrosivity and low corrosivity of indoor atmospheres are also included. Designed for use by materials, corrosion, civil and environmental engineers, designers, architects and restoration staff, this book will also be a useful tool for managers from different industrial sectors and auditors of environmental management systems. It will also be a suitable complementary course book for university students in all of the above disciplines.
