Book Description
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.

Book Description
This book discusses the detailed concepts of concrete and its development with pros and cons. Besides, the significance of various industrial wastes as partial replacements with concrete ingredients such as cement and aggregates are discussed. The creation of cement contributes to around 7% of carbon emissions into the atmosphere leading to greenhouse effect and global warming. Similarly, the wastes generated from various industries such as thermal, steel, ceramic, marble, paper and etc. shows the impact on atmosphere and leads to air pollution and land pollution. Thus, it is essential to focus on these wastes to use them in a profitable manner without compromising the current needs. This book discusses a few examples on studies of using various industry wastes as partial replacement of cement in concrete

Recycled Aggregates

Pages : 0
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"--
