This book was released on 2008 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cement is perhaps the most common soil stabilizer, often blended with soils at various proportions to increase strength and durability. However, there are concerns with regard to the impact of low curing temperature on strength and ultimate performance. The purpose of this study is to determine the impact curing temperature has on the unconfined compressive (UC) strength and stress-strain behavior of cement modified soil as well as to consider methods to improve performance in cold-weather conditions. The data indicate that curing soil-cement at lower temperatures will result in lower strengths. For example, the 7 day strength for samples cured at 25[degrees]F was less than the strength of samples cured at 50[degrees]F or 70[degrees]F by a factor ranging from 2-6. Likewise, the 7 day strength for samples cured at 35[degrees]F was less than the strength of samples cured at 50[degrees]F or 70[degrees]F by approximately 20-25%. Additionally, on the basis of 15 repeat tests for 3 & 7 day curing periods, for three different soils, results indicate that the mean strength at 3 days is 84-93% of that for 7 days, in support of a potential change in current subgrade evaluation practice predicated on the longer duration. The use of a calcium chloride (CaCl[subscript]2) solution as the molding moisture content was found to increase the UC strength by 20% for one soil/temperature condition but generally resulted in decreased strength at the concentration range (0.5 - 3.0%) tested. The use of CaCl[subscript]2 solution had a mixed impact on the maximum dry density (MDD), with overall changes between 2-3% of the MDD of the unmodified soil-cement control. Similarly, the optimum moisture contents (OMC) were generally within [plus or minus]2% of the OMC of the control. Analysis of the data suggests a threshold concentration for CaCl[subsript]2 efficacy, beyond which diminishing benefit transitions to deleterious performance.

Download or read book Assessment of the Performance of Engineered Waste Containment Barriers written by National Research Council and published by National Academies Press. This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.

Available in PDF, EPUB and Kindle. Book excerpt: More than ten years have passed since the first edition was published. During that period there have been a substantial number of changes in geotechnical engineering, especially in the applications of foundation engineering. As the world population increases, more land is needed and many soil deposits previously deemed unsuitable for residential housing or other construction projects are now being used. Such areas include problematic soil regions, mining subsidence areas, and sanitary landfills. To overcome the problems associated with these natural or man-made soil deposits, new and improved methods of analysis, design, and implementation are needed in foundation construction. As society develops and living standards rise, tall buildings, transportation facilities, and industrial complexes are increasingly being built. Because of the heavy design loads and the complicated environments, the traditional design concepts, construction materials, methods, and equipment also need improvement. Further, recent energy and material shortages have caused additional burdens on the engineering profession and brought about the need to seek alternative or cost-saving methods for foundation design and construction.
