Über dieses Buch

The need to establish material cycles in the building industry is undisputed. Knowledge on this topic is available in many places: In this book it is summarised and systematized. After a general overview of the quantities generated, recovery rates and areas of application of recycled building materials, the current processing steps on which recycling is based and the possibilities for influencing the product properties are discussed. Furthermore, recycling building materials are characterized and their fields of application are presented. The starting point is always the original building material, which is later found in the construction waste. The focus is on the structural properties. The environmental aspects, which have determined the discussion for years, are shown to the necessary extent. The book concludes with a chapter that presents new developments in processing technologies and analyses the potential of construction waste as a source of raw materials.

Chapter 1. Material Cycles
Abstract
Material cycles are essential to maintain the stable state of nature. The chemical elements circulate in different binding forms and aggregate states between the different reservoirs of the biosphere, hydrosphere, lithosphere, pedosphere and atmosphere, thus ensuring stability and compensating for changes over longer periods of time.

Chapter 2. Material Flow Management
Abstract
Construction and demolition waste is generated during the construction, renovation or elimination of a structure. A distinction is made between two approaches toward the removal of buildings or constructions.
Anette Müller, Isabel Martins
Chapter 3. Regulations for the Handling of Construction and Demolition Waste
Abstract
The proper handling of construction and demolition waste requires compliance with several laws and regulations, ranging from the formulation of policy objectives and measures to the specific rules for transport, treatment and recovery.

Chapter 4. Processing of Construction and Demolition Waste
Abstract
The objective of processing is the production of recycled building materials with defined properties from the secondary raw material construction and demolition waste. On the one hand, this concerns the particle size distribution, which must correspond to the requirements for the respective field of application.

Chapter 5. Plants for the Treatment of Construction and Demolition Waste
Abstract
On account of the very different composition of the species grouped under the term “Construction and Demolition Waste”, there are also differences in the plants used for their treatment. The differentiation between the plants for the treatment of mineral building rubble and those for construction site waste is mandatory due to the different composition of the materials.

Chapter 6. Recycling of Reclaimed Asphalt
Abstract
Asphalt as a material has its model in the natural “earth pitch” that originates from crude oil. Such natural asphalts were already used about 5000 years ago by the Babylonians and Sumerians to waterproof buildings. Artificial asphalt was introduced in the middle of the nineteenth century after bitumen could be produced from crude oil.

Chapter 7. Recycling of Concrete Rubble
Abstract
The term “concrete” refers to both a material principle and a certain building material. The material principle “concrete” includes all materials that consist of a bulk material whose particles are cemented by a binder and thus consolidated. In the building material concrete, this principle is realized by combining aggregates as particulate component with cement as binder.

Chapter 8. Recycling of Masonry Rubble
Abstract
Masonry is a composite consisting of masonry building materials bound together by mortar. Masonry building materials may be clay bricks, calcium silica bricks, aerated autoclaved concrete blocks or blocks of lightweight or normal concrete. Today, standardized masonry building materials are used.
Anette Müller, Isabel Martins
Chapter 9. Recycling of Other Types of Construction Waste
Abstract
The waste that arises during construction activities consists mainly of the construction materials asphalt, concrete and different masonry bricks. These are the main focus of recycling. In addition, construction and demolition waste contains a number of other components in much smaller quantities.
Anette Müller, Isabel Martins
Chapter 10. Advanced Recycling
Abstract
Since the beginning of “modern” recycling in the early 1980s, there have been attempts to improve the recycling rates and the quality as well as the level of products. In processing technology, this mainly concerns the crushing process and the sorting technology. On the product side, solutions are being sought for previously non-recyclable materials, in order to make landfilling superfluous.
