Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is to improve dredged marine sediments with lime for potential use in earthfill works. Dredging work is usually necessary for coastal construction work and this material should be removed in an economical way. Marine clay samples used in the study were dredged in Gemlik Bay near Bursa, in Turkey. Geotechnical tests were conducted to determine the properties of the natural clay samples, including classification tests, unconfined compression (UC) and California bearing ratio (CBR) tests. The optimum lime content by weight was determined as 5 % using the Eades and Grim pH method, Atterberg limits and unconfined compression strength tests. Standard and modified Proctor tests were conducted to determine optimum water content and maximum dry density of the soil. Maximum dry density values decreased, optimum water content values increased, and Proctor curves becomes flatter with the addition of lime. Because the natural water content of the clay is around 40 % and the optimum water content of the samples with lime is around 16 %, not only hydrated lime but also quicklime is used for the improvement and drying of the marine clay soil. The original unconfined compressive strength and CBR value of the dredging soil were close to zero because of high water content. One month after improvement by lime, the unconfined compressive strength value reached 550 kPa and soaked CBR value was 35 without swelling. Unconfined compressive tests and CBR test results demonstrate that this type of marine clay can be improved with lime and can be economically utilized as a fill material in earthfill works.

Book excerpt: Technical Report from the year 2017 in the subject Engineering - Geotechnology, grade: B+, , language: English, abstract: Treating marine clay is important for further advancement in construction and other infrastructure. Marine clay known as sort of clay found both in the littoral and in a few seaward ranges. Based on the objective of this study, the sample will be classified based on AASTHO and USCS classification systems by using Atterberg limits test (liquid limit and plastic limit) and sieve analysis test, where Unconfined Compressive Strength test (UCS) and California Bearing Ratio test (CBR) tests were conducted to determine the strength before and after adding different percentages of lime and OPC cement.

Available in PDF, EPUB and Kindle. Book excerpt: Significant changes in the geotechnical characteristics of a highly sensitive, cemented, marine clay (Champlain clay) were recorded following its treatment with hydrated lime (by mechanical mixing). Increase of the liquid and plastic limit, decrease of the sensitivity, and also increase of the unconfined compression strength were observed. Following the lime treatment, the clay also became nonerodible. The improvement of the geotechnical characteristics are dependent of the lime concentration; however, it seems that a peak is reached for about 3 to 4 percent lime concentration, above which no significant increase can be detected. These improvements are also curing time dependent.

Available in PDF, EPUB and Kindle. Book excerpt: Lime is commonly used to improve the engineering behavior of marine clay. But there is a need to investigate the lime-attributed changes in a particulate system in a marine environment. Lime columns 50 mm in diameter and 500 mm in length were installed in test tanks 600 mm in diameter at a depth of 550 mm, while lime injection was attempted in a test tank, 1000 by 1000 by 750 mm. The present investigation deals with experimental work carried out in the laboratory using lime column and lime injection techniques to stabilize an Indian marine clay in a salt water environment. Different inorganic additives were used with lime as column filler material to study the effect of lime-attributed changes occurring in the particle growth of soil systems. Grain-size distribution tests and SEM technique were carried out to study the lime-induced changes on the constituent particles. The test results indicate that there is an increase in the size of clay particles towards silt or fine sand fraction due to lime treatment. The formation of aggregates due to lime-soil reactions can be seen in the micrographs of different lime-treated soil systems, and the same has been confirmed using the SEM technique.

This book was released on 2020-05-12 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents experimental work done to investigate the efficacy of different additives, viz., lime and Quarry Dust, in stabilizing the marine clay, thereby, improving the strength, swell characteristics of the marine clay. A systematic methodical process was followed, involving experimentation in the laboratory under controlled conditions. It was observed that 7.5% lime treatment as individually and with the combination of 25% Quarry Dust with marine clay has effectively improved the laboratory CBR value. It was noticed from the laboratory investigations of the cyclic plate load test results that, the load carrying capacity of the treated marine clay subgrade model flexible pavement has been increased by 254% at OMC and 225% at FSC when compared with untreated marine clay subgrade model flexible pavement.
