Reijm, Cornelis (author)Argillaceous (clay-rich) host formations for radioactive waste geological repositories are extensively researched for their capability to decrease the hydraulic conductivity of fractures over time (i.e. self-sealing). This self-sealing behavior is beneficial in the context of radioactive repositories as the excavation of these spaces unavoidably...bachelor thesis 2021

Bloem, Hugo (author)In the Westerwald area clay quarries are in production. In order to assess the stability of the slopes the geotechnical characterisation of these quarries needs to be improved. This report provides the justification for a working plan for a thorough but quick assessment of existing slopes in clay mines. Literature is consulted for the...bachelor thesis 2017

Miedema, S.A. (author)This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the...book 2013

Miedema, S.A. (author)In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. The productions (and thus the dimensions) of the excavating equipment range from mm3/sec - cm3/sec to m3/sec. In oil drilling layers with a thickness of a magnitude of 0.2 mm are cut, while in dredging this can...book 2015

Pham, P.V. (author), van der Star, WRL (author), van Paassen, L.A. (author), Ye, G. (author)Rice husk ash is a promising pozzolanic material produced from rice husk burning and has significant potential a sustainable replacement for cement in construction and ground improvement applications. In this study the effect of burning conditions on the ash reactivity and its potential for soil stabilization applications have been investigated...book chapter 2015

Schadee, L.W. (author), Hoefsloot, F.J.M. (author)In the Bloemendalerpolder two test embankments were constructed in 2010 to study the long term behaviour of embankments on very soft soils with respect to settlement and lateral pile loading resulting from horizontal soil deformations. A detailed description of the test embankments, performed soil investigation, laboratory tests and...conference paper 2015

Sui, Shiyu (author), Georget, Fabien (author), Jiang, Jinyang (author), Scrivener, Karen (author)Chloride binding is an important factor for chloride transport in cementitious materials, which can fix the chloride on the solid phase and decrease the free chloride content. As an alumina-rich supplementary cementitious material, calcined clay can be applied to improve the binding capacity of the system. While the contribution of calcined clay...conference paper 2021

Stanier, S.A. (author), Hu, P. (author), Cassidy, M.J. (author)This paper demonstrates the use of a geotechnical drum centrifuge in the calibration of a model to predict the peak punch-through penetration (qpeak) resistance of a spudcan on sand overlying clay. A series of loose sand overlying clay tests was performed and combined with an existing database of tests performed on dense sand overlying clay. The...conference paper 2012

Seawsirikul, S. (author), Chantawarangul, K. (author), Vardhanabhuti, B. (author)Excessive differential settlement along bridge approach is commonly found in the lower central region of Thailand. To overcome the differential settlement problem, engineers have developed different types of bridge approach structure and improved design procedures. Two types of bridge approach structure are currently used in Thailand, including...conference paper 2015

Nagy, G. (author), Nagy, L. (author)When it comes to flood protection, the established method is to use impermeable material in dikes, to prevent seepage. This material is usually some kind of clay soil which is considered as impermeable and erosion-resistant. Dispite that, in many occasions not only seepage, but the failure of the dam occured due to surface erosion, because these...conference paper 2015

De Nijs, R. (author), Kaalberg, F. (author), Osselaer, G. (author), Couck, J. (author), Van Royen, K. (author)In order to relieve the busy traffic arteries of Antwerp (Belgium), the closing of the ring around Antwerp was put to study by BAM (Beheersmaatschappij Antwerpen Mobiel). The design of this construction requires detailed insight in the behaviour of the overconsolidated Boom clay layer during and after dewatering and removal of the covering soil...conference paper

Buragohain, P. (author), Vardon, P.J. (author), Hicks, M.A. (author)Disposal of spent nuclear fuel and long lived radioactive waste in deep clay geological formations is one of the promising options worldwide. In this concept of the geological disposal system, the Boom Clay is considered as a potential host rock when designing a generic waste repository in the Netherlands.

Gonthier, Julien Nicolas (author), Wilson, William (author), Georget, Fabien (author), Scrivener, Karen (author)The incorporation of supplementary cementitious materials (SCMs) in cement pastes enables both decreasing CO2 emissions and increasing the concrete durability, notably with a better resistance against chloride ingress and thus retarding the chlorideinduced corrosion of steel rebars. Nevertheless, a better understanding of the chloride fixation...conference paper 2021

Zhao, G. (author), Visser, P.J. (author), Vrijling, J.K. (author)This paper describes the hydrodynamic erosion process of undisturbed clay due to the turbulent flow, based on theoretical analysis and experimental results. The undisturbed clay has the unique and complicated characteristics of cohesive force among clay particles, which are highly different from disturbed clay and non-cohesive sand. Based on...conference paper 2011

(author)Excavation of clayey soils by mechanical tools is often hindered by the stickiness of the clay on metal parts. Hindrance may occur at the cutting tool itself, or during the subsequent transport of the soil through the excavation system. The effects of stickiness were also experienced in a recent tunnel boring project carried out in The...conference paper 1998

Due to the elimination of formwork during the layer-by-layer casting process, the printed material should have favorable elastic properties and green strength at the fresh state.
