This book was released on 2012 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has become an important aspect of developed countries throughout the world. Sustainability is the ability to use byproducts and or waste materials from industry and recycle these materials in such a way that the application of the materials provides a beneficial use in the manufacturing or construction sector. As the United States and the rest of the world continue to grow, so too does the demand on the limited natural resources throughout the world. It is this demand on the resources that has brought the idea of sustainability to the forefront of research and design. The transportation industry continues to incorporate sustainability into its projects. The industry is constantly trying new and innovative ways to recycle materials that would otherwise be sent to a landfill. Slag, a byproduct from the production of steel, is one of these materials. The transportation sector has used slags as aggregates for subbase and base layers in roads. Some slags, like blast furnace slag, have been used in portland concrete cement (PCC) applications as well. The focus of this research is to investigate the feasibility of using steel slag as an aggregate for use in portland concrete cement. An important aspect of this research was to complete a comprehensive review of other research that has been conducted on the use of steel slag as an aggregate. The literature reviewed included of laboratory studies that focused on the physical, mechanical, chemical, and expansive characteristics of the steel slag. The research on the use of steel slag was gathered from 16 different countries, which include the United States, Spain, Japan, China, Germany, Finland, and Saudi Arabia. Some of these studies have found that properly treated slag may be non-expansive and used in PCC. The possible expansion of the steel slag is the most important characteristic. The expansion of the steel slag aggregate can have detrimental effects on a pavement. This research investigated some of the treatment processes that are being used to alter the composition of the slag so that it is no longer expansive. It also examines testing methods used to test for the expansion of the steel slag. Seven State Department of Transportation specifications were also reviewed. Some DOT's allow its use as an aggregate in asphalt pavements but do not allow its use in portland concrete cement. A review of the ASTM standards relating to the use of the slag as an aggregate was also completed in this study. Different slag associations like the National Slag Association and the Australian Slag Association were contacted during this research, as well as 19 different steel companies, to try and get an understanding of the public perception of the use of the steel slag as an aggregate in PCC, and also to try and locate possible case studies. Several case studies were identified, and two of them resulted in a failure of the pavement. In those cases it is unknown what, if any, treatment process was used on the slag prior to its use in the portland concrete pavement.

Download or read book Broader Use of Steel Slag Aggregates in Concrete written by and published by . This book was released on 2008 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steel slag is an industrial byproduct obtained from the steel manufacturing industry. It is produced in large quantities during the steel-making operations which utilize Electric Arc Furnaces (EAF). Steel slag can also be produced by smelting iron ore in the Basic Oxygen Furnace (BOF). Steel slag can be used in the construction industry as aggregates in concrete by replacing natural aggregates. Natural aggregates are becoming increasingly scarce and their production and shipment is becoming more difficult. Steel slag is currently used as aggregate in hot mix asphalt surface applications, but there is a need for some additional work to determine the feasibility of utilizing this industrial by-product more wisely as a replacement for both fine and coarse aggregates in a conventional concrete mixture. Most of the volume of concrete is aggregates. Replacing all or some portion of natural aggregates with steel slag would lead to considerable environmental benefits. Most of the natural aggregates in the state of Ohio are shipped in from out of the state, whereas large steel slag deposits are locally available. The primary aim of this research was to evaluate the durability of concrete made with steel slag aggregates. This research has shown that replacing some percentage of natural aggregates by steel slag aggregates causes negligible degradation in strength. It is shown that as the amount of steel slag is increased beyond 75%; the workability of the concrete mixture became an important issue which eventually requires larger amounts of water reducing admixtures to achieve a minimum slump. The results showed that replacing about 50 to 75% of steel slag aggregates by volume for natural aggregates will not do any harm to concrete and also it will not have any adverse effects on the strength and durability.

This book was released on 1989 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall scope of this study was to evaluate the use of Portland cement for upgrading low quality aggregate encountered locally in Ohio. The primary targets of this investigation were to determine the optimum cement to be used in the form of an admixture or optimum cement and water-cement ratio for coating aggregates, optimization of mix parameters, reliability of performance evaluation, and the prediction of pavement performance compared to conventional bituminous concrete mixtures. Generally stating, treated low quality aggregates if used in bituminous concrete pavement with low volume traffic, will show beneficial effects in pavement structural life and performance, as opposed to virgin aggregate mixes.

Download or read book Metallurgical Slags written by Nadine M. Piatak and published by Royal Society of Chemistry. This book was released on 2021-08-04 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgical slags are generated as a by-product of smelting during ironmaking, steelmaking, and the production of ferroalloys and non-ferrous metals. The formation conditions result in complex chemical and mineralogical characteristics unique to slags alone. Historically slags have been discarded as a waste product and, through release of potentially toxic trace elements, represent a hazard to the environment and human health. However, increasingly we are realizing the resource potential of what was previously thought of as waste, thus reducing the environmental impact and taking a step closer to a circular economy. This book is a definitive reference on the environmental geochemistry and resource potential of metallurgical slags by summarizing processes for the generation of slags, describing their chemical and mineralogical characteristics, outlining the fundamental geochemistry that propels slag weathering, and illustrating the utilization of slags. Particular attention is given to the value of slags in modern society as they are widely used as construction materials in civil engineering, and as an irreplaceable filter in sequestering excess nutrients, pathogens, metal and/or organic contaminants, and even greenhouse gases. The latest developments on recovering residual valuable metals in slags, including new techniques for extracting by-product elements needed for green and frontier technologies, are revealed. This book is essential reading for environmental geochemists, geologists, metallurgists, mining and civil engineers, waste and resource managers, and all those interested and inspired by a circular economy and minimizing our environmental footprint on planet Earth.
