Part two reviews key steps in handling construction and demolition waste. It begins with a comparison between conventional demolition and construction techniques before going on to discuss the preparation, refinement and quality control of concrete aggregates produced from waste. It concludes by assessing the mechanical properties, strength and durability of concrete made using recycled aggregates. Part three includes examples of the use of recycled aggregates in applications such as roads, pavements, high-performance concrete and alkali-activated or geopolymer cements. Finally, the book discusses environmental and safety issues such as the removal of gypsum, asbestos and alkali-silica reaction (ASR) concrete, as well as life-cycle analysis of concrete with recycled aggregates.Handbook of recycled concrete and demolition waste is a standard reference for all those involved in the civil engineering sector, as well as academic researchers in the field. - Summarises key recent research in recycling and reusing concrete and demolition waste to reduce environmental impacts and meet national, regional and global environmental targets - Considers techniques for managing construction and demolition waste, including waste management plans, ways of estimating levels of waste, the types and optimal location of waste recycling plants - Reviews key steps in handling construction and demolition waste

Recycled Aggregates


Book Description

"With the rapid rise in our needs and requirements, the amount of waste generated by modern cities is also increasing at an unprecedented rate. This problem is global in nature and most countries around the world need appropriate waste management strategies. These measures include disposal and the 3Rs (reduce, reuse, and recycle). Each of these strategies has its own share of pros and cons. An increasing emphasis is being placed on the application of the 3Rs, especially from the environmental perspective. Construction & demolition (C & D) waste is generated when new infrastructure is built and/or older structures are demolished or renovated. Hundreds of millions of tons of such waste are generated worldwide annually, making it one of the most significant waste generating activities in the world. One way to take care of a significant fraction of this waste is as recycled aggregates (RA), wherein the waste is crushed to the dimensions of coarse and fine aggregates and is used for various activities, most notably in manufacturing of concrete. Other uses may include landfilling, manufacturing of tiles, bricks, pavement blocks, etc. Recently, other types of wastes such as used PET bottles have also been studied as a source of recycled aggregates. This book deals with the various socio-economic, technical, environmental, and policy issues related to the application of various types of recycled aggregates in different countries around the world. This is a continually evolving area of applied research which needs further emphasis not only from researchers, but planners and regulators as well"--
