These soils can exhibit low bearing strength, high volumetric instability, and freeze/thaw or wet/dry durability problems. Cement stabilization offers opportunities to improve these soils conditions. The objective of this study was to develop relationships between soil index properties, unconfined compressive strength and cement content. To achieve this objective, a laboratory study was conducted on 28 granular and non-granular materials obtained from 9 active construction sites in Iowa. The materials consisted of glacial till, loess, and alluvium sand. Type I/II Portland cement was used for stabilization. Stabilized and unstabilized specimens were prepared using Iowa State University 2 in. by 2 in. compaction apparatus. Specimens were prepared, cured, and tested for unconfined compressive strength (UCS) with and without vacuum saturation. Percent fines content (F200), AASHTO group index (GI), and Atterberg limits were tested before and after stabilization. The results were analyzed using multi-variate statistical analysis to assess influence of the various soil index properties on post-stabilization material properties. Results indicated that F200, liquid limit, plasticity index, and GI of the materials generally decreased with increasing cement content. The UCS of the stabilized specimens increased with increasing cement content, as expected. The average saturated UCS of the unstabilized materials varied between 0 and 57 psi. The average saturated UCS of stabilized materials varied between 44 and 287 psi at 4% cement content, 108 and 528 psi at t 8% cement content, and 162 and 709 psi at 12% cement content. The UCS of the vacuum saturated specimens was on average 1.5 times lower than that of the unsaturated specimens. Multi-variate statistical regression models are provided in this report to predict F200, plasticity index, GI, and UCS after treatment, as a function of cement content and soil index properties.

These soils can exhibit low bearing strength, high volumetric instability, and freeze/thaw or wet/dry durability problems. Cement stabilization offers opportunities to improve these soils conditions. The Iowa Department of Transportation (DOT) is considering the use of portland cement as an additive for stabilizing embankment materials in situ. The objective of this study was to develop relationships between soil index properties, unconfined compressive strength and cement content. To achieve this objective, a laboratory study was conducted on 28 granular and non-granular materials obtained from 9 active construction sites in Iowa. The materials consisted of glacial till, western Iowa loess, and alluvium sand. Type I/II portland cement was used in this study.

Available in PDF, EPUB and Kindle. Book excerpt: Although conventional improved soil using cement has high strength, a maximum strength can be induced by a small strain, causing cracks. Thus, such improved soil is not considered to be fit for core materials (i.e., impervious materials) for earth dam embankments. We have developed a method to repair embankments with crushed and compacted soil utilizing earth dam mud soil. This method enables embankments which rarely crack to be constructed. The improved soil was produced in the following manner. First, the stabilized soil was cured for a few days. The soil was then crushed, plowed, compacted, and re-stabilized, resulting in an improved soil that, although it had lower strength, at the maximum strength can only be generated by a large strain. In this paper, mechanical tests for soil specimens prepared in a laboratory and obtained from actual embankments were used to obtain the curing times till crushing, and the strength and deformation characteristics of the crushed-compacted soil. In addition, we carried out a dry-wet cycling test for endurance for the crushed-compacted soil, and examined the mechanical characteristics. Finally, we describe some actual examples where the present method has been applied.

Available in PDF, EPUB and Kindle. Book excerpt: The pneumatic flow mixing method was developed to stabilize dredged soil and surplus soil for promoting their beneficial use in 1999. The pneumatic flow mixing method is a new type of the ex-situ cement stabilization techniques, in which dredged soil and surplus soil is mixed with a relatively small amount of chemical binder without any mixing paddles and blades in a pipeline. When a relatively large amount of compressed air is injected into the pipeline, soil can be separated into small blocks. When binder is injected into the pipeline, the soil block and binder are thoroughly mixed by means of turbulent flow generated in the soil block during transporting. As this method has many benefits − rapid and large scale execution can be conducted with low cost − it has been applied to many land reclamation projects, backfilling behind earth retaining wall projects and shallow stabilization projects using dredged soils and surplus soils. The Pneumatic Flow Mixing Method is a useful reference tool for engineers and researchers involved in admixture stabilization technology everywhere, regardless of local soil conditions and a variety in applications.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the international edition of the proceedings of IS-Seoul 2011, the Fifth International Symposium on Deformation Characteristics of Geomaterials, held in Seoul, South Korea, in September 2011.The book includes 7 invited lectures, as well as 158 technical papers selected from the 182 submitted. The symposium explored ideas about the complex load-deformation response in geomaterials, including laboratory methods for small and large strains; anisotropy and localization; time-dependent responses in soils; characteristics of treated, unsaturated, and natural geomaterials; applications in field methods; evaluation of field performance in geotechnical structures; and physical and numerical modeling in geomechanics. These topics were grouped under a number of main themes, including experimental investigations from very small strains to beyond failure; behavior, characterization and modeling of various geomaterials; and practical prediction and interpretation of ground response: field observation and case histories. Both the symposium and this book represent an important contribution to the exchange of advanced knowledge and ideas in geotechnical engineering and promote partnership among participants worldwide.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the second half of a diverse collection of chapters in the field of materials and infrastructures in transport systems, which illustrate the technological and methodological innovations required to rise to the challenge of building more sustainable transport infrastructures for the future. The authors explore the potential of these sustainable solutions to improve the performance and efficiency of materials and infrastructures, with a reduced environmental impact and lower cost. Theoretical and practical case studies address a variety of topics including circular economy and sustainability, the impacts of climate change, durability, lifecycle, auscultation and the monitoring of infrastructures. This book provides transport researchers and professionals with a better understanding of the current and future trends in these innovative fields, enabling them to put into practice new technologies and methods of design and management, so that new solutions can become current practices to truly improve modern transport systems.
