Book Description
At the turn of the 20th century, industrial manufacturing was expanding dramatically while factory buildings remained fire-prone relics of an earlier age. That is, until a 28-year-old civil engineer finally achieved what engineers around the world had unsuccessfully attempted. Working in his brother’s basement in Detroit, Julius Kahn invented the first practical and scientific method of reinforcing concrete with steel bars, which finally made it possible to construct strong, fireproof buildings. After Kahn founded a company in 1903 to manufacture and sell his reinforcement bars, his system of construction became the most widely used throughout the world. Drawing upon Kahn’s personal correspondence, architectural drawings, company records, and contemporary news and journal articles, Michael G. Smith reveals how this man—whose family had immigrated to the US to escape antisemitism in Germany—played an important role in the rise of concrete. Concrete not only turned the tide against widespread destruction of buildings by fire, it also paved the way for our modern economy. Concrete Century will delight readers intrigued by architecture and construction technology alike with the true origin story of modern concrete buildings.
Waste Materials Used in Concrete Manufacturing

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.

Reinforced Concrete and the Modernization of American Building, 1900-1930
Author: Amy E. SlatonPublisher: JHU Press
ISBN: 0801872979
Category : Technology & Engineering
Languages : en
Pages : 280
Book Description
Examining the proliferation of reinforced-concrete construction in the United States after 1900, historian Amy E. Slaton considers how scientific approaches and occupations displaced traditionally skilled labor. The technology of concrete buildings—little studied by historians of engineering, architecture, or industry—offers a remarkable case study in the modernization of American production. The use of concrete brought to construction the new procedures and priorities of mass production. These included a comprehensive application of science to commercial enterprise and vast redistributions of skills, opportunities, credit, and risk in the workplace. Reinforced concrete also changed the American landscape as building buyers embraced the architectural uniformity and simplicity to which the technology was best suited. Based on a wealth of data that includes university curricula, laboratory and company records, organizational proceedings, blueprints, and promotional materials as well as a rich body of physical evidence such as tools, instruments, building materials, and surviving reinforced-concrete buildings, this book tests the thesis that modern mass production in the United States came about not simply in answer to manufacturers' search for profits, but as a result of a complex of occupational and cultural agendas.
