Limsiri, Cheevin (author)Soil-lime improvement is a common most effective me.fooimprove wet soft clay; many factors are involved in achieving the improvement. Mixing is one of those. The degree of pulverization plays an importance role in the efficiency of the improvement. The strength of treated soil depends on the lump size. A high degree of pulverization is expensive...report 2002

Kooistra, A. (author), Verhoef, P.N.W. (author), Broere, W. (author), Ngan-Tillard, D.J.M. (author), van Tol, A.F. (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

Hal, V.V. (author)Vietnam is an agricultural country where rice is the main crop cultivated in the Red river delta in the North and in the Mekong delta in the South. Both deltas refer to lowland. However, the degree of development is clearly different between the two deltas. In the Red river delta, the dike system as well as the canal networks have been...report 1996

Anonymus, N.N. (author)De redenen voor het uitvoeren van het onderzoek zijn gelegen in het feit dat voor de beoordeling van de kwaliteit van klei altijd is uitgegaan van de kennis en ervaring uit het verleden. Dit betekent dat vooral gekeken werd naar de samenstelling van de lutum- en zandfracties. Bij vergelijking van de eisen die daarvoor door verschillende...report 1996

Anonymus, A. (author)The current report is a Technical Report in which the results of various studies are brought together and placed in some sort of logical context. The aim of the report is to give insight into the properties of clay that are important for dike construction and to give direction to an unequivocal evaluation of clay. Based on the functions to be...report 1996

De Wit, P.J. (author)A research project was carried out at the Delft University of Technology in order to study the interaction between waves as weil as a current and a muddy bed. For this purpose several experiments were made on two artificial clays, namely China Clay and Westwald Clay. The results of the experiments on China Clay were reported by De Wit (1994). In...report 1994

De Wit, P.J. (author)The rheological behaviour of three artificial muds was determined using a rotational viscometer. First some characteristics of the viscometer used were rneasured. For want of an appropriate calibration tluid, the viscosity of demineralized water was determined. The result agreed very well with what could be expected from literature. Then the...report 1992

De Wit, P.J. (author)In this report an overview will be given of the basic properties of (suspended) clay particles. In section 2 the structure of clay minerals will be described. The forces between suspended particles (section 3) and the possible consequences of them, flocculation or deflocculation (sections 4 and 5) will be discussed next. Section 7 will deal with...report 1992

Verhoef, P.N.W. (author)Review of the application of the Methylene Blue adsorption test (titration spot method) applied to geomaterials (soils and rocks). With this method the Cation Exchange Capacity (CEC) of fine soils or fine grounded rock powder can be determined. Swelling clays have a high CEC and even small quantities (less than 1 mass % can be detected by this...report 1992

Bruinsma, R. (author)The behavior of the gunny bags under strong currents has been investigated in a flume on a scale of 1:1 . In the first test series a dam was built up with gunny bags only. The bags in the dam are quite stable up till a velocity of ca 2.60 m/s. With larger velocities the current is removing the bags to such an extend, that the flow cross-section...report 1985
