Available in PDF, EPUB and Kindle. Book excerpt: Embankment subgrade soils in Iowa are generally rated as fair to poor as construction materials. 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.

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.
Book Synopsis Applicability of Cement-Stabilized Mud Soil as Embankment Material by : S. Tani
Download or read book Applicability of Cement-Stabilized Mud Soil as Embankment Material written by S. Tani and published by . This book was released on 2006 with total page 21 pages. 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.

Book excerpt: The Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and d

Download or read book Soil Stabilization with Cement and Lime written by Philip Thomas Sherwood and published by Stationery Office Books (TSO). This book was released on 1993 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil stabilization is the process whereby soils and related materials are made stronger and more durable by mixing with a stabilizing agent. These techniques are used for road construction in most parts of the world, although the circumstances and reasons for resorting to stabilization vary considerably.

Book Synopsis Valorization of Dredged Sediments as Sustainable Construction Resources by : Amine El Mahdi Safhi
Download or read book Valorization of Dredged Sediments as Sustainable Construction Resources written by Amine El Mahdi Safhi and published by CRC Press. This book was released on 2022-08-31 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Valorization of Dredged Sediments as Sustainable Construction Resources provides a comprehensive and up-to-date overview of research on the reuse of sediments as a raw material for civil engineering fields. Dredging is increasing in scale worldwide, while deep sea disposal is being eliminated and landfill disposal is becoming less sustainable. Yet these sediments offer a potentially useful resource for constructing pavements, soil, bricks, ceramic and clinker, for they provide fine and lightweight aggregates, supplementary cementitious materials and geopolymer binders. This has sparked considerable research on valorization, which is presented here. Covers the main re-uses of sediments and the valorization required Focuses on state-of-the-art research on practical guidance Discusses limitations and future perspectives for sediments valorization The book suits researchers and students working in the area, as well as industrial engineers and professionals working on recycling and dredging.
