This book was released on 2013-10 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Indiana, the steelmaking industries and power plants generate large quantities of steel slag, blast furnace slag and fly ash every year. The excess of these underutilized industrial by-products are stockpiled and eventually landfilled at disposal sites. Use of steel slag, fly ash and blast furnace slag in road applications, such as in subgrade stabilization projects, can be a cost-effective alternative to lime stabilization in some cases. In addition, use of large quantities of these underutilized industrial by-products in these types of applications helps to reduce the need for new disposal sites and to conserve natural resources. The main objectives of this research were to evaluate the feasibility of using soil-steel slag-Class-C fly ash and soil-steel slag-blast furnace slag mixtures in subgrade applications and to implement the selected mixture as a subgrade material in a road construction project of INDOT. In order to achieve these goals, in situ clayey soils, collected from a prospective implementation site, were characterized through a series of laboratory tests which included specific gravity, grain size distribution, Atterberg limits, compaction and unconfined compressive strength. Two types of steel slag mixtures were evaluated for use in subgrade stabilization applications: i) steel slag-Class-C fly ash mixtures and ii) steel slag-blast furnace slag mixtures. The mechanical properties of soil-5% steel slag-5% Class-C fly ash, soil-7% steel slag-3% Class-C fly ash, soil-8% steel slag-2% Class-C fly ash, and soil-7% steel slag-3% blast furnace slag mixtures were determined through compaction and unconfined compression tests. CBR swelling tests were also performed to assess the swelling potential of the mixtures. The optimum moisture content and maximum dry unit weight of the in situ clayey soil samples were 13% and 18.56 kN/m3 (118.2 pcf), respectively. Based on the results of the long-term CBR swelling tests, the maximum swelling strain of the compacted soil samples was approximately 0.41 %. The average unconfined compressive strength of the in situ soil samples was 282.9 kPa (41 psi). Unconfined compressive strength tests performed on various mixtures at different times indicated the occurrence of stronger cementitious reactions in the soil-steel slag-Class-C fly ash mixtures than in the soil-steel slag-blast furnace slag mixtures. The two-day and seven-day unconfined compressive strength of the compacted soil-7% steel slag-3% Class-C fly ash mixture were 820 kPa (119 psi) and 886 kPa (128 psi), respectively. The maximum 1-D swelling strain of the soil-7% steel slag-3% Class-C fly ash mixture was 0.13 %. The soil-7% steel slag-3% Class-C fly ash mixture was selected as the most suitable and cost-effective subgrade material for the implementation project. The implementation project for the soil-steel slag-Class-C fly ash mixture was located at the intersection of 109th Avenue and I-65, near Crown Point, Indiana. The pre-mixed 7% steel slag-3% Class-C fly ash mixture was used to stabilize the in situ subgrade soils of some sections of the I-65 ramps located in the SW and NW quadrants of the intersection of 109th Avenue and I-65. Field compaction quality control was done by performing DCPTs and nuclear gauge tests. Cracks or signs of distress were not observed on the subgrade before base course and concrete placement. The soil-steel slag-Class-C fly ash stabilized subgrade performed satisfactorily.

Book excerpt: Since it was first recognized as a mineral admixture for concrete in the 1930's, fly ash has been the subject of worldwide study as researchers work to maximize its economical and environmental benefits. In recent years, investigations have focused on the physical, chemical and mineralogical characteristics of fly ash and their specific correlation to the performance of concrete. This book collects the latest results from these various studies and offers a complete review of the advantages of fly ash as an admixture in concrete, including strength development and improved chemical resistance and durability. A review of the current international standards on fly ash usage is provided, in addition to an extensive reference list and a complete survey of various other fly ash products, such as bricks, mineral wool and gypsum wall boards, as well as the use of fly ash in waste management.

Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the results of a two part research program on several laboratory air-entrained concrete mixtures designed to contain increasing amounts of moderately cementitious Class C fly ash. In the first part of the paper, a Type A admixture was used in half of the mixtures, treating both the portland cement Type I and fly ash (15% calcium oxide). In the second part of the paper, three other Class C fly ashes (9 to 12% calcium oxide) were extensively tested in concrete that contained a Type A admixture (but this time treating only the cement). Two very high lime fly ashes (25 to 30% calcium oxide) were also tested in concrete mixtures.

Book Synopsis Effect of Class C Fly Ash on the California Bearing Ratio Behavior of Soil-Fly Ash Mixes and Layered Systems by : B. Leelavathamma
Download or read book Effect of Class C Fly Ash on the California Bearing Ratio Behavior of Soil-Fly Ash Mixes and Layered Systems written by B. Leelavathamma and published by . This book was released on 2005 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly ash is a waste material from thermal power plants that occupies large extents of precious land and causes land, water, and air pollution. Hence attempts are made to use fly ash effectively instead of dumping it. Among the various possible uses, bulk utilization is possible only in geotechnical applications. Research work is being carried out on the addition of fly ash to improve the soil in road construction. But a thorough mixing of bulk quantities of fly ash and soil is not possible in the field. Hence, an attempt has been made to study the California Bearing Ratio (CBR) behavior of soil and fly ash (class C) in layers (fly ash on top) and the same is compared with the CBR of soil-fly ash mixes. The present paper deals with the experimental study of the CBR behavior of black cotton soil-Neyveli fly ash systems (layers and mixes). The study concludes that black cotton soil can be improved by layering with Neyveli fly ash, solving the strength problem of black cotton soil as well as the disposal problem of fly ash.
