Über dieses Buch

Concrete is the most used man-made material in the world since its invention. The widespread use of this material has led to continuous developments such as ultra-high strength concrete and self-compacting concrete. Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste focuses on the recent development which the use of various types of recycled waste materials as aggregate in the production of various types of concrete.

By drawing together information and data from various fields and sources, Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste provides full coverage of this subject. Divided into two parts, a compilation of varied literature data related to the use of various types of industrial waste as aggregates in concrete is followed by a discussion of the use of construction and demolition waste as aggregate in concrete. The properties of the aggregates and their effect on various concrete properties are presented, and the quantitative procedure to estimate the properties of concrete containing construction and demolition waste as aggregates is explained. Current codes and practices developed in various countries to use construction and demolition waste as aggregates in concrete and issues related to the sustainability of cement and concrete production are also discussed.

The comprehensive information presented in Recycled Aggregate in Concrete: Use of Industrial, Construction and Demolition Waste will be helpful to graduate students, researchers and concrete technologists. The collected data will also be an essential reference for practicing engineers who face problems concerning the use of these materials in concrete production.

Chapter 1. Sustainable Development in Concrete Production
Abstract
Environmental issues such as climate change and associated global warming, depletion of natural resources and biodiversity, water and soil pollutions, generation of huge amounts of waste materials and their disposal are some of the great challenges faced by present-day civilisation. The emission of large amounts of particulate materials and various noxious gases including CO2, the major greenhouse gas, into the atmosphere, due to rapid industrial and population expansions, is a major environmental concern and urgent action is necessary to control it. Each of these issues creates serious crisis to the future development of humankind if they are not tackled properly. The evaluation of the impact of the current developments on the environment is therefore an important agenda for present-day policy-makers and several initiatives have already been taken to tackle the problems related to these issues. Thus the term “sustainable development” was developed, which proposes a developing society, where people will live in a healthy environment with improved economic and social conditions.

Chapter 2. Industrial Waste Aggregates
Abstract
The aggregates typically account for 70–80 % of the concrete volume and play a substantial role in different concrete properties such as workability, strength, dimensional stability and durability. Conventional concrete consists of sand as fine aggregate and gravel, limestone or granite in various sizes and shapes as coarse aggregate.

Chapter 4. Use of Industrial Waste as Aggregate: Properties of Concrete
Abstract
As indicated in an earlier section, aggregates account for the largest part of the concrete volume and therefore play a substantial role in almost all concrete properties such as workability, strength, dimensional stability, and durability. Recently, several waste materials have been studied to be used as aggregate in concrete. The use of waste as aggregates can consume vast amounts of waste materials as this is the major component of cement mortar and concrete.

Chapter 6. Methodologies for Estimating Properties of Concrete Containing Recycled Aggregates: Analyses of Experimental Research
Abstract
The use of concrete now accounts for such a high level of consumption of non-renewable natural materials that, in some countries, there is already a shortage of these products. The demolition of concrete structures produces waste that is difficult to store owing to the lack of proper dumping places and high transportation and storage costs. The concern with the need of raw materials and the production of enormous quantities of waste has led to several studies on solutions to these problems. A number of studies have recently been published on the properties of recycled aggregates and this aggregate-based various concretes.

Chapter 7. Concrete with Recycled Aggregates in International Codes
Abstract
Despite being an ancient activity, the management of waste produced in construction activities did not get much attention until the last decade. Construction and demolition waste (CDW) is not subjected to management practices as with municipal solid waste, perhaps due to the higher toxicity of the latter as compared with the former’s. Recently, rapid urban expansion, stringent environmental regulations and the scarcity of land filling areas as well as the natural resources over-exploitation led to the need of using CDW as aggregate for construction purposes.
