Recent developments in bio-based soil improvement techniques include the use of the bacterially mediated process of denitrification to alter engineering properties of soils. Pham (2017) used the denitrification process to stimulate the production of gas and precipitation of calcium carbonate as a soil improvement method. The ability to...

Peatlands in the Netherlands suffer from continued surface subsidence and accumulation of suspended sediments which leads to poor water quality. Excess suspended sediments are currently being deposited in depots on peatlands as a sustainable method for reusing sediment and to compensate for surface subsidence. The general consensus of...

Land reclamations in deltaric areas provide space to meet the demand for a safe place to live and work. Sand, a traditional filling material in some locations is becoming scarcer. An alternative filling material is mud. Mud consists of clay, silt, sand, organic material, water and gas. Therefore, it is a versatile material and difficult to...

A study regarding the use of additives to stabilise dredged material has been conducted. The research objectives were to find additives, describe the effects the additives have on the dredged material, explain these effects and the necessary properties to deposit the stabilised material at a high rate, being 2000 m3 per hour. All these...

An underwater slope can collapse by liquefaction, wedge failure or breaching. Breaching is the most unknown process and has a low predictability. Dredge mining is strongly influenced by the breaching process. If breaching can be accurately predicted, the efficiency of the dredging production can be maximised.It is the objective to know what...

Solid bulk cargo liquefaction is a serious problem in the shipping industry. Numerous capsized ships have been reported as a result of liquefied cargo. Only between 2009 and 2016 nine ships sunk, causing 100 casualties. Most accidents did happen with nickel ore transport but other fine grained solid bulk cargoes report accidents as well. The...

Sand sculptures are an inspiration source for an environmentally friendly building material, consisting only of sand, clay and water. The art of sand sculpting is generally dealt with low technical consideration. There is a need of comprehensive technical look on this topic in order to make standards for sand-sculpting. This study involves...

A demand to use mud as fill material for land reclamations has emerged over the past years. Such reclamations start with pumping a muddy suspension into an area enclosed by dikes. The particles in suspension then settle to form a mud layer, so that the supernatant can be removed. This filling process may be repeated several times to completely...

Bank protections are currently constructed with stone, wood, concrete and steel. NETICS has introduced a sustainable and commercially very attractive alternative called the GEOWALL. The goal of this study is to find a viable field of application within the quay structures by considering the arising challenges of a larger scale wall. Additionally...

CoRncrete is a corn starch based bio-material formed by mixing corn starch with water and sand, and heating the mix in a microwave or oven. This heating process results in the formation of a hardened material. A constant corn starch to sand proportion of 1:5 has been adopted in this study. The transformation of CoRncrete from a semi-solid to a...

Bentonite is a clay that is used in many industrial applications. Company X required an investigation on the bentonite that is mined by Company Y. Currently Company X produces cat litter only from her bentonite, but other applications might be of economical interest to the company. After scoping down to 4 applications other than cat litter ...

This research aims to provide an understanding of the behaviour of co-disposed coarse (sand) and fine (clay and silt) tailings when discharged into an onshore dredge pond, and the dependence of that behaviour on the sediment composition. This understanding contributes to the ultimate goal of finding a method by which fine tailings can be...

A research was undertaken to find the suitability of Turkish calcium bentonite from the mines of a Company. Four samples of bentonite mines in the {\"U}nye region are researched, the M1, M2, M3 and M4 mine. The suitability of drilling fluid, foundry sand, soil improvement and bleaching earth applications is found through research on the...

This research deals with the evaluation of earthquake induced liquefaction susceptibility of carbonate sands, used as hydraulic fill. Existing evaluation methods are based on in-situ penetration tests (CPT, SPT etc.) and on seismic case histories at sites where silica sands are predominant. These methods cannot be implemented on carbonate sands,...

Controlled calcium carbonate precipitation can be used for various applications. Calcium carbonate precipitation occurs when dissolved calcium and carbonate are mixed at concentrations which exceed the solubility of calcium carbonate. With alternate injection of pulses of calcium chloride and sodium carbonate solutions in time through a porous...

Om baggerslib te kunnen hergebruiken is het belangrijk dat bekend is hoe lang het duurt totdat het gedroogd is. Om dit te kunnen testen is van het baggerslib uit het Delftse Hout een monster genomen van zowel fijn als grof slib. De hoofdvraag hiervan was: hoe snel gaat het dit droogproces en hoe hangt dat af van de samenstelling, in het...

In this thesis a method is developed to regain the geotechnical behaviour of undisturbed quick clay by reconstitution of remoulded natural quick clay samples. Quick clay is characterised by a high sensitivity; the ratio between the undisturbed and remoulded strength is very high. Because of the high water content they behave fluid-like after...

Potentially unstable salt caverns of AkzoNobel need to be stabilised with a suitable backfill material in order to prevent surface subsidence. These caverns are currently filled with Carbonate and Gypsum slurry, a residual product of the brine purification process, but a new backfill material is being developed for stabilisation purposes. At the...
