Plastic pollution is a complex environmental problem. The use of recycled plastics in the modification of concrete materials has a dominant role to play in the move towards sustainable construction. Reuse of Plastic Waste in Eco-efficient Concrete presents the latest research findings on the application and use of recycled plastic waste in sustainable construction. Divided over four parts, the chapters cover various techniques for processing and separation of plastic wastes; use of recycled plastics as aggregates in modified concrete; as well as lightweight reinforced concrete applications too. There is also an entire section dedicated to asphalt mixtures. The book provides technological solutions on how recycled plastic wastes can be applied in concrete manufacturing. It will be a valuable reference source for academic and industrial researchers who are working with waste materials and the use of recycled plastics in concrete, as well as for civil and structural engineers, polymer production technologists, and concrete manufacturers. - Describes the main types of recycled plastics that can be applied in concrete manufacturing - Presents, state-of-the art knowledge on the properties of conventional concrete with recycled plastics - Discusses the technological challenges for concrete manufacturers for mass production of recycled concrete from plastic waste - Covers lifecycle cost analysis, production challenges, and long-term performance analysis

Presently most electrical/electronic equipment (EEE) is not designed for recycling, let alone for circulation. Plastics in these products account for 20% of material use, and through better design, significant environmental and financial savings could be gained. Technological solutions and circular design opportunities already exist, but they haven’t been implemented yet. Some challenges, such as ease of disassembly, could be resolved through better communication and by sharing learnings across the value chain.Instead of WEEE, we should focus on developing CEEE: Circular Electrical and Electronic Equipment.The case examples of this report show how different stages of the lifecycle can be designed so that plastics circulation becomes possible and makes business sense. It is time to take a leap in material flow management and scale up these circular solutions across the industry.

The environmental aspects involved in the production and use of cement, concrete and other building materials are of growing importance. CO2 emissions are 0.8-1.3 ton/ton of cement production in dry process. SO2 emission is also very high, but is dependent upon the type of fuel used. Energy consumption is also very high at 100-150 KWT/ton of cement produced. It is costly to erect new cement plants. Substitution of waste materials will conserve dwindling resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials for making cement. To some extent, it will help to solve the problem otherwise encountered in disposing of the wastes. Partial replacement of clinker or portland cement by slag, fly ash, silica fume and natural rock minerals illustrates these aspects. Partial replacement by natural materials that require little or no processing, such as pozzolans, calcined clays, etc., saves energy and decreases emission of gases. The output of waste materials suitable as cement replacement (slags, fly ashes, silica fumes, rice husk ash, etc.) is more than double that of cement production.These waste materials can partly be used, or processed, to produce materials suitable as aggregates or fillers in concrete. These can also be used as clinker raw materials, or processed into cementing systems. New grinding and mixing technology will make the use of these secondary materials simpler. Developments in chemical admixtures: superplasticizers, air entraining agents, etc., help in controlling production techniques and, in achieving the desired properties in concrete.Use of waste products is not only a partial solution to environmental and ecological problems; it significantly improves the microstructure, and consequently the durability properties of concrete, which are difficult to achieve by the use of pure portland cement. The aim is not only to make the cements and concrete less expensive, but to provide a blend of tailored properties of waste materials and portland cements suitable for specified purpose. This requires a better understanding of chemistry, and materials science.There is an increasing demand for better understanding of material properties, as well as better control of the microstructure developing in the construction material, to increase durability. The combination of different binders and modifiers to produce cheaper and more durable building materials will solve to some extent the ecological and environmental problems.

This book describes how, given the global challenge of a shortage of natural resources in the 21st century, the recycling of waste concrete is one of the most important means of implementing sustainable construction development strategies. Firstly, the book presents key findings on the micro- and meso-structure of recycled aggregate concrete (RAC), while the second part focuses on the mechanical properties of RAC: the strength, elastic modulus, Poisson’s ratio, stress-strain curve, etc. The third part of the book explores research on the durability of RAC: carbonization, chloride penetration, shrinkage and creep. It then presents key information on the mechanical behavior and seismic performance of RAC elements and structures: beams, columns, slabs, beam-column joints, and frames. Lastly, the book puts forward design guidelines for recycled aggregate concrete structures. Taken as a whole, the research results – based on a series of investigations the author has condu cted on the mechanical properties, durability and structural performance of recycled aggregate concrete (RAC) over the past 10 years – demonstrate that, with proper design and construction, it is safe and feasible to utilize RAC structures in civil engineering applications. The book will greatly benefit researchers, postgraduates, and engineers in civil engineering with an interest in this field.
